Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It should be noted that the terms "first," "second," and the like herein are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic flow chart of a picture retrieval method provided by the present invention, as shown in fig. 1, the method includes

steps

110, 120, 130 and 140. The method flow steps are only one possible implementation of the invention.

Step 110, receiving a search keyword.

Specifically, the execution subject of the picture retrieval method provided by the embodiment of the invention is a picture retrieval device. The picture retrieval means may be implemented by software, for example a picture retrieval program running in a computer; the device may also be a device for performing the picture retrieval method, such as a mobile terminal, a tablet computer, a desktop computer, or a server.

The application scene of the picture searching method provided by the embodiment of the invention is that a user uses a plurality of chat software to exchange information, and certain text information appears in a chat record in a picture form. The user needs to search for the information in the form of pictures according to the search keywords.

The search keyword is a word or a combination of words input by the user for searching information. The user can input the search keywords in the picture search device through the modes of physical key input, touch operation input, voice input and the like.

And 120, matching the search keywords with the keywords corresponding to each picture, and determining the picture global names of the target pictures corresponding to the search keywords and the text content recognition results of the target pictures.

Specifically, after receiving the search keyword, the search keyword may be matched with the keyword corresponding to each picture. The matching method can adopt a semantic similarity matching method. Semantic similarity between the search keywords and the keywords corresponding to each picture can be calculated. The higher the semantic similarity, the higher the matching degree between the search keywords and the keywords corresponding to each picture. The preset semantic similarity threshold value can be set, and if the semantic similarity between the keyword corresponding to any picture and the search keyword is greater than the preset semantic similarity threshold value, the keyword corresponding to the picture can be considered to be matched with the search keyword, and the picture can also be considered to be a target picture corresponding to the search keyword.

The naming of pictures by the chat software may have a conflict, i.e. the same naming convention is adopted, resulting in different pictures being given the same name. In addition, due to the personal habits of the user, there may also be a case where the same name is used for different pictures. In order to ensure that each picture has a unique identifier in the computer system, a picture global name may be added to each picture. The picture global names are used for guaranteeing global uniqueness of the picture names.

The text content recognition result is a recognition result of the text content in the picture. For example, OCR character recognition (Optical Character Recognition) may be used to recognize each picture to obtain a character content recognition result.

The keyword, the global name of the picture and the text content recognition result can be stored as index information of the picture. When the search keywords are matched with the keywords corresponding to any picture, a picture global name and a text content identification result can be obtained according to the index information of the picture.

Here, the text content recognition result is used as a part of the index information, and can be fed back directly without going through other search steps, so that the response speed of the picture search device can be improved.

And 130, acquiring the target picture and the basic information of the target picture based on the picture global name.

Specifically, the global picture name is used as a global unique identifier of the picture, and the target picture and basic information of the target picture can be obtained by searching in a file system. The basic information is attribute information related to the chat software, the original name of the picture, the creation date of the picture, and the like.

And 140, displaying the target picture, and identifying the text content of the target picture and the basic information.

Specifically, the target picture, the text content identification result of the target picture and the basic information can be displayed to the user in the visual interface of the picture retrieval device, so that the user can view the target picture and view the text content identification result of the target picture, and corresponding chat software, chat time and the like can be further positioned according to the basic information, thereby obtaining richer chat information.

According to the picture retrieval method provided by the embodiment of the invention, the retrieval keywords are matched with the keywords corresponding to each picture, and the picture global names of the target pictures corresponding to the retrieval keywords and the text content recognition results of the target pictures are determined; acquiring a target picture and basic information of the target picture according to the picture global name; displaying a target picture, and a character content identification result and basic information of the target picture; through the text recognition of the picture and the keyword retrieval, the text processing is carried out on the picture content, so that the chat picture is retrieved according to the text recognition content in the picture, the user does not need to search and position the picture in the computer by means of memory, the information retrieval efficiency is improved, and the management level of the picture in the computer is improved.

It should be noted that each embodiment of the present invention may be freely combined, exchanged in order, or separately executed, and does not need to rely on or rely on a fixed execution sequence.

In some embodiments, the method further comprises:

In particular, different chat software creates separate folders in the computer system for storing text, pictures, files, etc. in the chat log. An independent picture library can be created, pictures in chat records of all chat software are copied and then stored in the picture library, and renaming is carried out on each stored picture to obtain the picture global name of the picture.

And when the pictures are stored in the picture library, the attribute information of each picture, including the original name, the picture global name, the picture creation time, the affiliated chat software, the source storage directory and the picture storage directory, can be obtained, and the information is used as the basic information of the pictures, so that a picture information table of the pictures is generated. The picture information table contains each attribute (field), and the type (data format) and related description of each attribute, as shown in table 1.

Table 1 picture information table

The text recognition can be carried out on each picture, the text content in the picture is recognized, and the text content recognition result of each picture is obtained. For example, an identification engine may be created in a computer system. The engine can be a background silent program, and obtains a storage catalog of the newly added picture by scanning a picture information table of the newly added picture in a picture library, reads the newly added picture under the catalog, and carries out OCR character recognition on the picture. OCR text recognition is divided into four steps of image preprocessing, text detection, text recognition and language model correction, and finally, a text content recognition result converted into a text form is obtained.

The text content recognition result of the picture can be added into the picture information table through the picture global name, and the original picture information table is expanded, as shown in table 2.

Table 2 Picture information table (expansion)

The word segmentation can be carried out on the text content recognition result of each picture, and the keywords corresponding to each picture are obtained. The word segmentation method may include a dictionary-based word segmentation method, a statistical-based word segmentation method, a deep learning-based word segmentation method, and the like. For example, a vocabulary of words may be obtained. The word segmentation table is a list of complete Chinese and English words recorded in the text. The word content recognition result can be split according to the word segmentation table, and the split result is a set of words or phrases, and the set is a subset of the word segmentation table.

The word segmentation result can be used as a keyword for searching the picture. An Inverted index (Inverted index) may be created for a picture to enable retrieval of the picture based on the value of the attribute. The attribute here is a keyword.

And generating inverted indexes of the pictures according to the picture global names, the text content identification results and the keywords of the pictures, as shown in table 3.

TABLE 3 inverted index Table

On the basis of word segmentation results, an inverted index is established, and the index correlates keywords, text content identification results and picture basic information, specifically, the inverted index table and the picture information table are provided with picture global names.

In some embodiments, storing pictures in chat records of a plurality of chat software to a picture library includes:

traversing the chat record storage files of each chat software, and copying the pictures with the picture creation time smaller than or equal to the current picture acquisition time and larger than the last picture acquisition time in the chat record to a picture library.

Specifically, a plurality of picture acquisition times can be set, and pictures in each chat software are copied to a picture library in a mode of acquiring incremental pictures.

And determining the acquisition time range of the picture according to the current picture acquisition time and the last picture acquisition time. And copying the pictures with the picture creation time smaller than or equal to the current picture acquisition time and larger than the last picture acquisition time in the chat record into a picture library as acquired objects.

The local storage directory (i.e., the source storage directory of pictures) may be configured for each chat software. The delta pictures are then retrieved under each local storage directory. The local storage directory configuration of each chat software is shown in table 4.

Table 4 local storage directory configuration table of chat software

For full scope collection, the configured directory should be a top-level directory containing all chat records under which to traverse, a specific traversal algorithm consults the depth-first traversal or breadth-first traversal of the tree. And when the traversal starts, a newly added picture (calculated according to the picture creation time) in the time difference range between the last picture acquisition time and the current picture acquisition time is the picture range acquired at the current time. And copying the pictures to a local catalog of the picture library, renaming the picture names, and ensuring the global uniqueness of the picture names in the whole picture library.

In the picture library, pictures can be stored according to different directory levels. The directory hierarchy can sequentially establish different directory hierarchies according to the chat software name and the creation time, and store pictures. The creation time can be divided into a date and a time. For example, for a certain picture, its picture library storage directory may be "picture library root directory/chat software directory/date directory/time directory".

In some embodiments, step 120 comprises:

under the condition that the search keywords are matched with any keyword in the inverted index of any picture, determining any picture as a target picture corresponding to the search keywords;

Specifically, each picture may correspond to a plurality of keywords. These keywords are recorded in the inverted index.

The search keywords can be matched with the keywords in the inverted index of each picture one by one, when the search keywords are matched with any keyword in the inverted index of any picture, the picture can be determined to be a target picture corresponding to the search keywords, and the picture global name and the text content identification result of the target picture are obtained according to the inverted index.

For example, according to the keywords input by the user, searching is performed in the inverted index table through the keyword field, if the keywords are matched, the content corresponding to the word content identification result field is pushed to the user interface for display, so that the user can quickly see the search result. And then, searching complete basic information in the picture information table according to the picture global name, pushing the basic information to a user interface again for displaying, and enabling a user to further position chat software and chat time according to the basic information, so that an original chat record can be searched in the chat software.

In some embodiments, step 120 is preceded by:

matching the search keywords with the history search keywords in each search history record;

when the search keyword matches with a history search keyword in any one of the search histories, a target picture and a text content recognition result and basic information of the target picture are determined based on the search histories.

Specifically, as the picture library increases, and each picture may correspond to a plurality of keywords, in order to improve the retrieval efficiency, each retrieval keyword and the corresponding retrieval result may be saved as a retrieval history.

After the user inputs the search keywords, the search keywords may be first matched with the history search keywords in each search history. If the search keywords are matched with the history search keywords in any search history record, the target picture and the text content identification result and the basic information of the target picture can be determined according to the search history record, and each picture in the picture library does not need to be searched one by one, so that the search efficiency is improved.

In some embodiments, the retrieval history is updated based on the steps of:

traversing each retrieval history;

and deleting the search history record when the search date and/or the repeated search times of any search history record meet the preset condition.

Specifically, the current search history may be generated according to the current search keyword, the current searched target picture, and the text content identification result and the basic information of the target picture. The retrieval history may be embodied in tabular form as shown in table 5.

Table 5 search history table

When each picture is searched, the picture is recorded in a search history record table corresponding to the picture, and if the picture is repeatedly searched, the repeated search times are updated.

The history records with longer retrieval time and less repeated retrieval times can be cleaned regularly according to the last retrieval time and the repeated retrieval times. The specific method comprises the following steps: traversing each retrieval history; and deleting the search history record when the search date and/or the repeated search times of any search history record meet the preset condition.

The preset conditions may be set as:

the time difference between the last retrieval time and the current time is greater than a first time difference threshold;

or the time difference between the last retrieval time and the current time is smaller than or equal to the first time difference threshold value and larger than the second time difference threshold value, and the repeated retrieval times are smaller than the first retrieval times threshold value;

alternatively, the time difference between the last retrieval time and the current time is less than or equal to a second time difference threshold, and the number of repeated retrieval times is less than or equal to a second retrieval times threshold.

The first time difference threshold is larger than the second time difference threshold, and the first retrieval times threshold is larger than the second retrieval times threshold. The above thresholds may all be set as desired.

For example, the first time difference threshold may be 3 months, the second time difference threshold may be 1 month, the first search number threshold is 3, and the second search number threshold is 1.

The apparatus provided by the embodiments of the present invention will be described below, and the apparatus described below and the method described above may be referred to correspondingly.

Wherein, the picture library, the OCR recognition engine and the search engine are core modules of the invention.

Fig. 3 is a second flow chart of the picture searching method provided by the present invention, as shown in fig. 3, the relationship and interaction flow of each module in the picture searching device are as follows:

(1) Picture library

The instant chat software can buffer the chat record under a certain directory of the local computer, the picture library supports the configuration picture directory, searches the files in the picture format from the directory, and copies the files to the picture library directory. The photo library also supports the classification management of the pictures in different dimensions, such as creating a two-level directory by "chat software name-picture creation time". When the picture enters the picture library, the basic information of the picture is stored in a picture information table, wherein the basic information comprises picture names, picture creation time, chat software, a picture original catalog and a picture storage catalog.

(2) OCR recognition engine

The engine is a background silent program, scans incremental pictures of a picture library at regular time, performs OCR (optical character recognition) on the pictures, and stores character content recognition results in a picture information table.

(3) Search engine

The search engine mainly comprises three functions: word segmentation, index maintenance and retrieval. The word segmentation is to split words or phrases of the picture recognition result by using a word stock; on the basis of word segmentation, the search engine establishes an inverted index, and the index correlates words or phrases with picture identification results and picture basic information. And during searching, reversely checking the character content recognition result and the picture basic information through keyword matching. The search results are pushed to the visualization interface.

(4) Storage warehouse

The repository is a database that stores primarily picture information and picture content identification results, search engine indexes, other relevant configuration and management data. The picture information is registered in the repository when the picture library collects pictures. After the OCR engine finishes the picture content recognition, the picture recognition result is pushed to a storage library, and the picture global name is associated with the registered picture basic information. The search engine builds an index and stores the index information in a library.

(5) Visual interface

The visual interface includes application configuration and management, search and result presentation. Application configuration and management is used for maintaining configuration information, such as configuring a picture storage catalog of chat software; or manage the pictures, such as manually confirming the OCR recognition result. The search and result presentation includes a search box and a result presentation portion. The user inputs the keywords in the search box, the visual interface pushes the keywords to the search engine, after the search engine finishes searching, the search result is pushed to the visual interface, the visual interface displays the search result, and according to the basic information of the pictures in the search result, the pictures are searched and displayed in the picture library.

Aiming at the Internet office scene, the embodiment of the invention solves the problem that the chat pictures in the chat software are difficult to search. The commonly used chat software is not self-contained and is based on the retrieval of the picture content, and the embodiment of the invention can be a supplement to the chat software function.

The embodiment of the invention carries out literal processing on the picture content based on OCR recognition and search engine technology and provides retrieval based on the picture content. When the user inquires the historical chat content, the search range is expanded from pure words to pictures, and the problem that the user can only search the historical chat pictures by memorization is solved.
