Sampling Effectiveness in Discovering Functional Relationships in Databases

In this section we discuss the accuracy of the dependency inference from samples through several experiments. In these experiments we use a union catalog database that contains bibliographic information about books and journals stored in Japanese universities. The data of this database is used for the online catalog. This database has been compiled by registering the bibliographic information of books and journals which the university libraries purchased. Currently about 350 universities participate in this union catalog database system and its size is growing by 66 Gbyte. In the experiments we used data of Japanese books in the database. This relation consists of about 100 attributes and contains about 1 million tuples. We selected 10 attributes from this relation whose values are less than 60 bytes because almost all values are different in long valued attributes and that does not make sense in FDs. The selected attributes include the author’s name, publisher, registered date and so on. As a result, the relation used in the experiments consists of 10 attributes and contains about 1 million records whose size is about 50M bytes.
Functional Architecture for Knowledge Search
Published in Denise Bedford, Knowledge Architectures, 2020
Search system processes revolve around one component – an index. An index helps us to locate important information in an asset. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Derived from Latin, an index means one who points out, an indication or a forefinger. Examples are a back-of-the-book (BOTB) index or a library catalog. In a traditional BOTB index, the headings will include names of people, places, events, and concepts selected by the indexer as being relevant and of interest to a possible reader of the book. The indexer may be the author, the editor, or a professional indexer working as a third party. The pointers are typically page numbers, paragraph numbers, or section numbers. A library catalog is another form of index. A catalog record contains authors, titles, subject headings, and pointers to where the item is found in the collection, either in the form of a call number or a weblink. Internet search engines (such as Google) and full-text searching help provide access to information but are not as selective as an index, as they provide non-relevant links and may miss relevant information if it is not phrased in exactly the way they expect.
Intelligent Agent Technology

Mobile agents travel on the computer network to go to the site of a server they need to use. The interaction with the server occurs at the server site, and then agents travel back to their origin to provide users the results. Essentially, mobile agents are a solution to the limited bandwidth of the network. By sending an agent to the server site, the amount of network traffic generated is minimized. For example, consider a library catalog server on the network. A nonmobile interface agent queries the server for certain items. The results of the query are returned to the agent. Suppose the desired item is not available at this server and the agent must query another server. In this case, the network transmission from the first server can be avoided if the agent were to visit the server site. Then, upon finding that the server does not have the desired item, the agent could travel to the second server site, and so on.

The recommendations regarding the type of information and processes that can facilitate the renovation and overcome the bottlenecks include the following: Pre-defined Building characteristics, to provide initial scenarios and an indication of cost and energy at the early stage, with minimum effort.Comprehensive building data checklist, considering the level of detail for said information at every step of the renovation process.Technical information on products, in form of a catalogue.The Construction team and the different suppliers should be involved earlier in the process.Clearly defined responsibilities of all stakeholders throughout the processCommunication channels and protocols between the design team and the client team, for solutions approval and execution
