    Abstract
    Searches conducted as part of the MEDLINE/Full-Text Research Project revealed that the full-text data bases of clinical medical journal articles (CCML (Comprehensive Core Medical Library) from BRS Information Technologies, and MEDIS from Mead Data Central) did not retrieve all the relevant citations. An analysis of the data indicated that 204 relevant citations were retrieved only by MEDLINE. A comparison of the strategies used on the full-text data bases with the text of the articles of these 204 citations revealed that 2 reasons contributed to these failure. The searcher often constructed a restrictive strategy which resulted in the loss of relevant documents; and as in other kinds of retrieval, the problems of natural language caused the loss of relevant documents.

    Abstract
    A bilingual Welsh-English full text database is planned for Inspection Reports of Her Majesty's Inspectors of Schools for Wales. Special requirements for free text retrieval in the Welsh language are identified, and practical solutions are proposed for problems arising from the use of standard text database products, some of which may also apply to other lesser-used languages

    Abstract
    State of the art review of the development of full text databases, encompassing: types of commercially available full text databases; online systems for full text databases; CD-ROM databases for full text databases; full text databases on magnetic discs or tapes; creation of full text databases; searching and display requirements for full text searching and software. Concludes that bibliographic information services without full text support solve only half of the retrieval problems

    Abstract
    At Rotterdam Ports Authority in the Netherlands the Habour information database includes a press cuttings service and various online databases. To enable research staff to have direct access to information the POINT (Point Information Net) was begun in 1993. Using Verity software POINT provides simultaneously full text searching on a range of databases. The software uses current Web indexing technqiues to overcome the problems of excessive recall and low precision. A key element is the system's ability to recognise word combinations

    4. Vermutlich wird sich aufgrund der genannten Gründe der Buchservice Volltextsuche als heterogen darstellen: Einige Verlage werden gar nicht mitspielen, andere werden ein Buch im Vollzugriff, ein anderes nur zum Teil, ein drittes nur als Metainformation usw. indizieren lassen. Dies wird letztlich ebenfalls die Trefferqualität schmälern, da der Nutzer dann wiederum wissen muss, genau welche Informationen und Texte ihm bei seiner Suche vorenthalten werden. Das gedruckte Sachbuch wird gegen seinen eigenen digitalen Klon ein Alleinstellungsmerkmal brauchen, um weiterhin attraktiv zu sein. 5. Ein solches Alleinstellungsmerkmal würde m.E. maßgeblich durch die Erstellung von gedruckten Registern bereits in der Druckausgabe erreicht werden. Damit würde die Druckausgabe tatsächlich an Wert gewinnen und der Buchkäufer erhielte einen echten Mehrwert. Zum einen spiegelt sich bereits in der Erstellung konventioneller gedruckter Register die zweite digitale Revolution wider: Moderne Registererstellung basiert heutzutage ebenfalls auf der digitalen Verwertung des Volltextes. Zum anderen erfordert das "Registermachen" zugleich die Erbringung jener o.g. sachdienlichen Mehrinformationen wie Verweisungsbegriffe, vernünftige Klassifizierungen, nicht-redundante Begriffsauswahl etc., die nur begrenzt automatisierbar sind und Fachwissen erfordern. Erst diese beiden Komponenten lassen die Indexierung schlussendlich zu einer hochwertigen Aufbereitung sequentieller Information werden. 6. Genau diese Mehr- und Metainformationen, die die vorausgegangene Erstellung eines Print-Vollregisters geliefert hat, lassen sich dann in den Suchalgorithmus der Online-Suche zur Qualitätssteigerung der Treffer einrechnen."
