FIG. 1 is a flow chart showing an embodiment of the present invention and an outline of the processing of a failure information search support method of the present embodiment.

As shown in FIG. 1, the failure information search support method according to the present embodiment receives a search formula input by a searcher,
In a fault information search system that displays fault search information search 2 and a search result display 3, a search formula is registered in a search formula case list 10 as a search formula case for each search purpose as a search formula case. Search process registration 5 in which the search process is registered in the search formula case list 10 in association with the registered search formula case when the purpose is changed, and as the next process, either search termination or related information search, narrowing search or range expansion search Next processing reception 6 to receive from the searcher whether or not the user wants to perform. When the search is completed, the search is terminated. In the case of related information search, a search expression candidate for related information 7 is displayed. Expression candidate presentation 8, in the case of expanded range search, search expression candidate presentation 9 for expanding the search range, the searcher selects a search expression from the presented search expression candidates, and selects Receiving 1 search expression searcher modified search expression was, and so repeat the search.

As shown in FIG. 2, the fault information search system includes a CPU 201, an input device 202, a communication device 203,
A CPU including a display device 204 and a storage device 205;
Reference numeral 201 denotes a search formula input by the searcher, searches for failure information, registers the search formula for each search purpose as a search formula case in the search formula case list 10, and registers when the search purpose is changed. The search process is registered 5 in the search expression case list 10 in association with the search expression case, presents search expression candidates for related information, presents search expression candidates for refinement, and presents search expression candidates for range expansion 9 I do.

A search formula candidate for related information is presented 7, a search formula candidate for narrowing down is presented 8, and a search formula for expanding a search range 9 is presented.

Next, a detailed description will be given of the search formula case list 10 for storing data necessary for the processing of the fault information search support method of the present invention.

The search formula case list 10 stores a list of search formula cases.

The search formula case includes a search formula case ID, an OR connection keyword, an AND connection keyword, a browse destination, and a search process.

The search formula case ID represents a symbol that uniquely indicates a search formula case.

An OR connection keyword is a set of a set of search keywords connected by OR in a search formula created for the same search purpose. For example, search expression 1 (ma OR mab),
Search formula 2 (ma OR mar) AND (ppm OR pmm OR ppp),
It is assumed that three search expressions of search expression 3 (ma OR mab) AND (tts OR tl) are created for the same search purpose. In this case, ma
And mab and mar are connected by OR, so OR1 = (ma, mab,
mar). Also, apart from ma, ppm, pmm, and ppp are connected by OR, so OR2 = (ppm, pmm, ppp
). In addition, since tts and tl are connected by OR separately from ma and ppm, OR3 = (tts, tl) is also displayed separately from ma and ppm. The OR1, OR2, and OR3 obtained in this way are called an OR connection set.

An AND connection keyword is a set of search keywords for each search expression including an AND connection created for the same search purpose.
An OR created by replacing the connection set with the same OR set
It is a set of connection sets. For example, search expression 1 (ma OR mab
), Search formula 2 (ma OR mar) AND (ppm OR pmm OR pp
p), search expression 3 (ma OR mab) AND (tts OR tl) three search expressions are created for the same search purpose.

In this case, the AN created for the same search purpose
The set of search keywords for each search expression including the D connection is (m
a, mar, ppm, pmm, ppp) and (ma, mab, tts, t
l), and the OR connection set is OR1 = (ma, mab, mar), OR2 =
(ppm, pmm, ppp), OR3 = (tts, tl), and when the search keyword is replaced with an OR connection set including the search keyword, (OR1, OR1, OR2, OR2, OR2) and (OR1, O
R1, OR3, OR3). AND1 = (OR
1, OR2) and AND2 = (OR1, OR3). The AND1 and AND2 obtained in this way are called an AND connection set.

The browsing destination stores the name of the information providing server, the location of the information providing server, the directory, and the file name as information that uniquely represents the data browsed from the search results by the searcher. '.' Is used as a delimiter between the name of the information providing server and the location of the information providing server, and '/' is used as a separating character between the information on the location, directory and file name of the information providing server. You. For example, the name of the information providing server is www, and the location of the information providing server is
f.co.jp, directory ma, file name mar.h
If it is tml, the browsing destination is stored as www.f.co.jp/ma/mar.html.

In the search process, when the purpose of the search by the searcher is changed, the search process is registered and the search expression case ID is registered.
In the column. For example, in one search process, a search formula case A2 is performed after a search formula case A1 and a search formula case A2
Is followed by the search formula case A3, P1 = (A2, A3) is stored in the search process of the search formula case A1. If a search formula case A3 is executed after a search formula case A1 in another search process, P2 = (A3) is stored separately from P1 in the search process of the search formula case A1. I do.

Next, the process of registering a search formula in the search formula case list 10 as a search formula case for each search purpose will be described in detail.

FIG. 4 is a flowchart showing a specific example of the purpose-specific search expression registration 4.

As shown in FIG. 4, the purpose-specific search formula registration 4 of the present embodiment performs the same purpose search formula case extraction 401, performs an OR connection keyword registration 402, performs an AND connection keyword registration 403, and performs browsing. Registration 404 is performed.

The same purpose search expression case extraction 401 is extracted by one of the following (M1) to (M5) or some combination depending on the difference in the definition that the purpose of the search expression is the same.

(M1) Two search formulas exist in the same search process, and the browsing destination browsed by the searcher from the search results for one search formula exists in the search results for the other search formula. In the case where the search purposes of the two search expressions are the same, in this case, it is included in the search expression examples created or extracted for the search expression that is received in the same search process received before the currently received search expression. If the browsing destination included in the search formula case is present in the search result by the currently received search formula, the search formula case including the browsing destination is fetched.

(M2) When two search formulas exist in the same search process, and a search keyword present in one search formula exists in the other search formula, the search purposes of the two search formulas are the same. In this case, in this case, the retrieval keyword included in the retrieval expression case created or retrieved for the retrieval expression of the same retrieval process received before the currently received retrieval expression is retrieved, and the retrieval included in the retrieval expression instance is performed. If the keyword is present in the currently received search expression, a search expression example including the search keyword is extracted.

(M3) The same search keyword exists in the two search formulas, and the browsing destination browsed by the searcher from the search results for one search formula is the searcher from the search results for the other search formula. If the search purpose of the two search expressions is the same, if the search purpose is the same as the browse destination, the search expression created or retrieved for the search expression received before the currently received search expression The browsing destination included in the search formula case is extracted, and if the browsing destination included in the search formula case exists in the currently received search formula, the search formula case including the browsing location is extracted.

(M4) When two search formulas exist in the same search process and the search keywords in one search formula exist in more than half of the other search formulas, the search purposes of the two search formulas are the same. If there is, in this case, the search keywords included in the search expression case created or extracted from the search expression received before the currently received search expression are extracted, and the search keywords included in the search destination case are currently received. If more than half of the search expressions exist, a search expression case including the search keyword is extracted.

(M5) When the searcher receives a request to perform a related information search as the next process, it is determined that the search formula received immediately before and the search formula received immediately after have different search purposes, and the next process is narrowed down. If you receive a search or expanded search from the searcher, and if the search expression received immediately before and the search expression received immediately after have the same search purpose, in this case, narrow down search as the next process Alternatively, if the searcher receives a request to perform a range expansion search, the search formula case created or extracted from the search formula received immediately before is extracted. If it is received from the searcher that the user wants to perform a related information search as the next process, no search expression case is extracted.

The range in which the same search process is considered when the purpose of the search is changed is one of the following (N1) to (N5) or a combination of some of them.

(N1) The range of the search process performed during one start of the fault information system is defined as a range.

(N2) The range of the search process performed by the same searcher is set as the range.

(N3) The range of the search process performed within a certain period of time is set as the range.

(N4) A search process performed by a searcher in the same group is defined as a range.

(N5) The search process performed by the same system is set as the range.

The OR connection keyword registration 402 creates an OR connection set of search expressions when a search expression case is extracted by the same purpose search expression case extraction 401 and adds the search expression to the OR connection set of the extracted search expression case. Is added, and if the search keyword is included in multiple OR sets,
Join the containing OR sets.

For example, if the OR set of the retrieved search expression cases is OR1 = (jn, jm), and the search expression is (tps OR tp OR t
ip) AND (jm OR jam), the OR set of the search expression is OR
2 = (tps, tp, tip), OR3 = (jm, jam).

When the OR connection set of the retrieval expression is added to the OR connection set of the retrieved retrieval expression case, OR1 = (jn, jm)
, OR2 = (tps, tp, tip), OR3 = (jm, jam)
It is.

Since the search keyword jm is included in the OR sets OR1 and OR3, they are combined, and OR1 = (jn, jm) and OR2 = (
tps, tp, tip) are obtained and registered.

If the search expression case is not extracted in the same purpose search expression case extraction 401, the OR connection keyword registration 402 creates a search expression case having no element, and replaces the search expression case ID with another search expression case ID. Is created with a symbol different from the above, an OR connection set of the search formula is created, and this is set as the OR set of the newly created search formula case.

The AND connection keyword registration 403 is to create an AND connection set of search expressions when a search expression case is extracted by the same purpose search expression case extraction 401 and to add the search expression to the AND connection set of the extracted search expression case. Is added, and if the OR sets are combined in the OR connection keyword registration 402, the name of the OR connection set of the AND connection set is also changed.

The AND connection keyword registration 403 is to create an AND connection set of search expressions when the same purpose search expression case extraction 401 does not extract a search expression case, and to create an AND connection set of the newly created search expression case. Set as a set.

In the browsing destination registration 404, the browsing destination browsed by the searcher in the search result for the received search formula is retrieved by the same purpose retrieval formula case retrieval 401 or O.
It is registered in the search expression case created in the R connection keyword registration 402.

The search process registration 5 registers a search process in the search formula case list 10 in association with the registered search formula case when the purpose of the search is changed. Search process is a search formula case
Expressed as an ID column.

For example, in one search process, a search formula case A2 is performed after a search formula case A1, and a search formula case A2
Is followed by the search expression case A3, P1 = (A2, A3) is stored in the search process of the search expression case A1. If a search formula case A3 is performed after a search formula case A1 in another search process, P2 = (A3) is stored separately from P1 in the search process of the search formula case A1. I do.

When a search formula candidate for related information search 7 is received from the searcher to perform a related information search as the next process, the search formula candidate 7 is input for the same search purpose as that of the search formula received from the searcher. The search process is extracted from the searched search expression cases, and the search expression of the search expression case included in the search process is presented to the searcher as a search expression candidate for related information search.

For example, a search formula example input for the same search purpose as the search formula received from the searcher is:
In the search formula example A1 shown in FIG. 3, the search process is P1 = (A2, A
3) When P2 = (A3), as shown in FIG. 5, the OR connection keywords of the AND connection keywords of the search expression case A2 and the search expression case A3 are replaced with OR connection between the elements of the OR connection set. A search formula candidate is displayed by displaying the search formula created by the AND connection in a tree shape.

The narrowing-down search expression candidate presentation 8 indicates that if the searcher receives from the searcher that the user wants to perform a narrowing search as the next process, the search input for the same search purpose as that of the search expression received from the searcher Search keywords and AND used in the search formula entered by the searcher in the formula case
The connected search keywords are extracted and presented to the searcher as search expression candidates for narrowing down.

For example, a search formula example input for the same search purpose as the search formula received from the searcher is:
In the search formula example A1 shown in FIG. 3, if the search formula is (ma OR mar), the OR connection set O to which the search keywords ma and mar belong
A retrieval formula created by extracting R1 and replacing the OR connection set of the AND connection set including the OR connection set OR1 with the OR connection between the elements of the OR connection set and performing an AND connection
(ma OR mab OR mar) AND (ppm OR pmm OR ppp) and (ma OR
mab OR mar) AND (tts OR tl) to display search expression candidates.

The search range expansion search formula candidate presentation 9 is input for the same search purpose as that of the search formula received from the searcher when receiving from the searcher that the user wants to perform the range expansion search as the next process. Search keywords used in the search formula entered by the searcher and O
The search keywords connected in R are extracted and presented to the searcher as search expression candidates for expanding the search range.

For example, a search formula example input for the same search purpose as that of the search formula received from the searcher is:
In the search formula example A1 shown in FIG. 3, if the search formula is (ma OR mar), the OR connection set O to which the search keywords ma and mar belong
R1 is extracted, and a search expression candidate (ma OR mab OR mar) created by OR-connecting the elements of the OR connection set OR1 is displayed to display search expression candidates.
