{ "item_title" : "Formal Semantics and Pragmatics for Natural Language Querying", "item_author" : [" James Clifford", "Clifford James", "C. J. Van Rijsbergen "], "item_description" : "This book discusses the connection between two areas of semantics, namely the semantics of databases and the semantics of natural language, and links them via a common view of the semantics of time. It is argued that a coherent theory of the semantics of time is an essential ingredient for the success of efforts to incorporate more 'real world' semantics into database models. This idea is a relatively recent concern of database research but it is receiving growing interest. The book begins with a discussion of database querying which motivates the use of the paradigm of Montague Semantics and discusses the details of the intensional logic ILs. This is followed by a description of the author's own model, the Historical Relational Data Model (HRDM) which extends the RDM to include a temporal dimension. Finally the database querying language QEHIII is defined and examples illustrate its use. A formal model for the interpretation of questions is presented in this work which will form the basis for much further research.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/0/52/160/274/0521602742_b.jpg", "price_data" : { "retail_price" : "59.00", "online_price" : "59.00", "our_price" : "59.00", "club_price" : "59.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
