COMPUTER-GASED INFORMATION RETRIEVALSYSTEM IN MEDICINAL AND AROMATIC PLANTSUSING A MINICOMPUTER HP-IOOO SYSTEM

An exp erimen tal information storage andretrieval system in the field of medicinal andaromatic plants, based on the database of Medi-cinal and Aromatic Plants Abstracts (MAPA)service of the Publications and InformationDirectorate is reported. The machine readable,database created from the first three 1982issues of MAPA is designed for searches bykeywords, first author, journal, language, andby subject groupings as followed in the printedversion of MAPA. The search can be eithersingle aspect of any of the above or in combi-nation of different searchable elements withBoolean logic. The programs have been developed in FORTRAN IVan a HP-1000 mini-computer system.

INTRODUCTION

A bimonthly abstracting journal (MAPA).covering the fields of medicinal and aromaticplants is being brought out by PID since 1979under its MAPIS service. Since its inception, thekeyword .indexes are being brought out by acomputer. The keyword index is given alongwith every issue of MAPA and the Decemberissue contains cumulated keyword and authorindexes. The data for both the author and thekeyword index entries are stored on magnetictapes for future cumulated indexes.

Computers are now being increasingly usedfor data processing and information retrievalallover the world. Some computer-aided indexesand directories have been brought out in Indiaby a few organizations concerned with scientificpublications and information dissemination [1-

6]. Now, an effort has been made to developan information retrieval system in medicinaland aromatic plants, after gaining experience inbringing out the computer-aided indexes, bystoring only the bibliographic details of all theabstracts on a magnetic tape. Such a database(DB) will be used to meet the requirements ofspecific technical queries and to bring outbibliographic lists on demand. The author indexentries could be generated from this DB it-self.

SYSTEM DESCRIPTION

The reported system christened as "COMPASS"(Computerized Medicinal Plants AbstractsSearching Service) is designed for a HP-1000minicomputer with 32K core memory, twomagnetic tape drives (800 bpi), one fl9PPYdrive (.5 MB), one card reader ano .a 400 lpmdot-matrix line-printer, FORTRAN IV being thehigher-level language available under RTE-M(II) operating system.

Searchable Elements of the Database

The main approach of searching the DB isthrough a set of descriptors. The subject con-~ent of MAPA abstracts cover wide spectrum ofphytochemistry, biochemistry, botany, medi-cine, pharmaceuticals, agriculture and othermiscellaneous subjects and no single compre-hensive thesaurus covering all the disciplines isavailable. In view of the cost and time con-siderations in terms of staff for developing acomprehensive thesaurus over so many broadfields, maintaining and updating, indexing is

done by assigning keywords mostly from thetitles without a controlled vocabulary. Wheretitles are vague, keywords from the abstractand/or original text are provided. Availablethesauri are used at the time of searching forincluding synonyms, broad terms and relatedterms etc. Thus, the concept is freely indexedin variant forms like verbs and nouns endingwith differences due to tense, person, numberetc. as well as adjectival and adverbial formswith some spelling variations in some cases.Right-hand truncation technique for searchingdescriptors is used optionally in the searchprograms to retrieve a concept which is indexedunder its variants as mentioned above. ThusTOXlC* is used in searches to retrieve thedocuments indexed under TOXIC, TOXICEFFECTS, TOXICITY etc. Broad conceptscan also be retrieved using the right-hand trun-cation. Similarly, using PAPAVER * for search-ing, all the documents related to the generap apouer will be retireved, although they areindexed under papaver braceatum, papaverrhocas and papaver somniferum and not sepa-rately under papaver.

In addition to the subject approach, search-es can also be conducted by journal name,language of the paper, first author and subjectgroupings as given in the printed version ofMAPA issues, like agronomy, botany, etc.either singly or in combination. A seven digitcode (the first character being the startingletter of the journal, followed by a 5-digitcode) is assigned for each journal with onecheck digit as the seventh character. For langu-age, the first three letters are used as the code.A four digit numeric code is assigned for thesubject groupings.

Main File (Bibliographic File): A programvalidiates the data for correct serial number,journal code, delimiters of institution, titleand journal. From this 160-byte records file,another program creates the main file with512-byte· record length, a sample of which isshown in Fig.3.

Inverted Files: An inverted file (File 1A) of 50-byte record length is created from the mainfile with the following forma t (Fig.4):

Bytes Description

9-48 Term (First Author or SubjectGrouping or ] oumal code orLanguage code)

49-50.

Another, inverted file (File 2A) is createdfor keywords with same 50-byte. format as

above containing "KW" in byte position 49-50(Fig.5). Both these inverted files are linkedwith the main file through the 8-digit No. ofyear, issue No. and abstract serial No.

Since controlled vocabulary is not utilizedfor indexing, the keywords are subjected to a"squeezing" procedure i.e. eliminating thespecial characters like blank, comma, hyphenand apostrophe and then sorted. This is donewith a view to get correct matching of freedescriptors mostly lifted from the titles forindexing. The descriptor to be used for searchis also squeezed before carrying out the searchfrom the sorted inverted squeezed files. Using"ANTI-INFLAMATORY ACTIVITY" for thesearch, the squeezing operation helps the re-trieval of all the following terms indexed as:

lists are punched in their normal form as 80-byte records using the key-to-tape machine. Theterms are then squeezed and generated as 50-byte records containing the term-type "KW"in the byte positions 49-50. The first authorentries art" also generated as similar 50-byte

The system is designed for batch processing ofthe queries. Since the available memory parti-LALA tion for a user program is around 12K in the

LA system, up to 10 queries can be processed at aLALA time. Each query can store relevant, document~~ numbers up to 250. Every volume of MAPA hasLA to be searched separately due to these con-t~ straints. About 4000 papers are covered in aLA volume. Each query can contain up to 180LA total descriptors in the programs developedAU at present which can be extended up to 600 ifAU necessary.AUAU Each query is analysed by the search editorsAU and terms of potential interest are collected.AUAU Thus, synonyms and related, terms etc. areAU added to the list from the subject knowledgeAU of the search editor as well as consulting someJC thesauri, classification schedules, subject in-JCJC dexes of related secondary journals etc. FromJC the knowledge of the terms used in indexing,JCJC words are truncated to improve the matchingJCJCJCJC

as already described. The truncated word isindicated by putting a star (*) as the last charac-ter as explained before. From a careful studyof the wording given in the query, key terms arerelated by adding the Boolean logical operators(OR, AND & ANDNOT) to provide the searchlogic. Each query is numbered with a threedigit number and each keyword is given anotherthree digit number for a given query. A sampleof terms used in a query with the query num-ber and the keyword numbers is shown inFig.6(a). The finalized terms are arranged inthe form of concept maps following the practicedescribed in the CAN/SDI manual [7] . Theterm type is not used at present in the searchingkey terms. The provision kept now will be usedlater on for specific purposes. A sample of 5test queries translated into the format of aconcept map along with the query logic used isshown in Fig.7. It is to be noted that apostrophesymbol (') is used in place of NOT symbol (-.)and "-" is used in place of 11IROUGH opera-tor (~) as they are not available on the HP con-sole keyboard. End of the search logic is indi-cated by the character question mark (?).

Searching Program

Search keywords are sorted on the term (Col-umns 7-46) in the beginning (Fig.6b). The searchprogram compares each descriptor with thatof File 2 (and File 1 if indicated) and outputson to another tape the hits as a ten byte re-cord, i.e. 3-digit query number, 4-digit abstractnumber and 3-digit keyword number. The

122

File 1 and File 2 are kept on the same tape reeland .provision is made in the search program toindicate the number of files to be searched. Incase the number of files is given as more than1, the search keyword tape is rewound andsearching starts afresh with all the given num-ber of files. If the searches contain a combina-tion of keyword and anyone or more of theother searchable elements, both the files willbe searched. In case the search(es) is (are)merely confined to keyword combinations,File 2 is only searched. The search keywordscan be given either on tape or on cards.

The hit records file is sorted on characters1-10. Using this sorted file, a search-Iogic-processing program requests to key in thesearch logic for each query. At the end ofprocessing the logic of all the queries, it storesthe abstract numbers of relevant documentsfor each query in the core. It also consolidatesthe number of citations to be output for all thequeries, using the main file sorted by the ANs,writes them on to a diskette (optionally to atape if they exceed 800 due to space con-straints on a single diskette). Then, the rele-vant documents for each query are output in acolumn width of 60 characters. In case, morethan 800 documents are written on to the tape,the tape is searched serially, the citations areprinted for one query, the tape is rewound andthe procedure is repeated as many times asthere are number of queries. Tli.e system flowchart for COMPASS is given in Fig.S. Asample output from five test queries (as shownin Fig.7) is given in Fig.9. All the programsdescribed above are in FORTRAN IV along witha number of assembler subroutines for stringmanipula tions.

CONCLUDING REMARKS

This system is initially designed for batchprocessing of queries over fixed intervals of timeusing the HP-I000 minicomputer with theconfiguration already described. The design ofthe system viz., the file organization, searchprocedure, final output of the citations is thusplanned in accordance with the capabilitiesof a minicomputer where large disc space and
