Information Retrieval - Semantic Search and NLP - Goker & Davies Editors:
This reading talks about the use of semantics in searches. It refers the major categories from the ontology perspective. These include schema-ontologies, topic-ontologies, and lexical ontologies. The schema-ontologies refer to ontologies which are close in purpose and nature to database and object-oriented schemata. The topic-ontologies refer to taxonomies which define hierarchies. Lexical-ontologies refer to lexicon with formal semantics.
Carl Grant on Information Retrieval systems in libraries:
The Orbis Cascade Alliance wrote a letter that states to Ex Libris and to Ebsco Information Services (EIS): This letter stated “We are writing to express our great concern about your failure to make EBSCO academic library content seamlessly and fully available via Ex Libris discovery services....We urge EBSCO and Ex Libris to quickly resolve this issue. Failure to do so is a disservice to your customers and the faculty, students, and researchers we serve.” This was important because it let people know that they need to do their research when purchasing a database. Libraries have to worry about what limitations are being forced on them.
