The difficulties of readily obtaining peripheral information and drawbacks of citation searches are discussed. A citation survey of inorganic chemistry journals is compared with previous studies. The publication of a chemical newspaper is proposed. (11 references) (Author)

The relevance assessments belonging to the Cranfield II document/query collection are shown to be faulty, in the sense that many" relevant documents were not so identified by the Cranfield judges. 9 references. (Author)

The indexing of Cranfield I and II is given and critical comments made of this indexing. Comparisons of Cranfield indexing to other types of indexing are made. (AB)

The complete report, ERIC document ED 022 494, is abstracted in the February 1969 "Research in Education.

Addresses the application of automatic classification methods to the problems associated with computerized document retrieval. Different kinds of classifications are described, and both document and term clustering methods are discussed. References and notes are provided. (Author/JD)

The present experiments were designed to study the effects of search term weighting based on very limited relevance information, supplied, for example, by one or two relevant documents. The tests simulated iterative searching as in an on-line system and show that even very little relevance information can be extremely valuable. A list of…

Discusses information retrieval techniques used on the World Wide Web. Topics include machine learning in information extraction; relevance feedback; information filtering and recommendation; text classification and text clustering; Web mining, based on data mining techniques; hyperlink structure; and Web size. (LRW)

Proposes a method to improve retrieval performance of the vector space model by using users' relevance feedback. Discusses the use of singular value decomposition and the latent semantic indexing model, and reports the results of two experiments that show the effectiveness of the proposed method. (Author/LRW)

This study examined the contribution to retrieval effectiveness (measured by recall and precision) of adding content-bearing information such as abstracts and tables of contents to bibliographic records. It was found that the addition of content-bearing information improves overall retrieval effectiveness. Improvement was primarily in terms of…

Describes a study that used the TREC information-retrieval test collection to evaluate Visual Information Retrieval Interfaces (VIRIs). Discusses multiple-similarity measures, scaling properties, and MLE (maximum likely method), and suggests that cosine-vector and overlap measures for similarity appear to recover optimal data relationships among…

Discusses the test collections developed in the TREC (Text REtrieval Conference) workshops for information retrieval research and describes a study by NIST (National Institute of Standards and Technology) that verified their reliability by investigating the effect changes in the relevance assessments have on the evaluation of retrieval results.…

Considers relevance and recall as measures of the effectiveness of information retrieval systems. Highlights include relevance judgments and information retrieval, including experiments with test collections; information retrieval and assessment of recall; and a comparison of two retrieval mechanisms using a new set of relevance judgments designed…

Discusses some of the work included in the sixth TREC (Text Retrieval Conference). Highlights include retrieval effectiveness and relevance feedback; linguistic phrase identification; word elimination; weighting; precision and recall; query concepts; ad hoc and Chinese retrieval; and cross lingual information retrieval. (LRW)

Considers some of the most fundamental problems in music information retrieval, challenging the common assumption that searching on pitch alone is likely to be satisfactory for all purposes. Discusses special issues related to polyphonic music, user-interface issues, and the notion of relevance for music information retrieval. (Contains 52…

We propose that the design and implementation of effective "Social Learning Analytics (SLA)" present significant challenges and opportunities for both research and enterprise, in three important respects. The first is that the learning landscape is extraordinarily turbulent at present, in no small part due to technological drivers.…
