Provide a DAML representation of the CIA World Fact Book. Temporal data (many values are tagged by year). Uncertainty (some values are tagged by "est."). The ability to add semantic structure to a widely referenced data source. The basic data structure is fairly simple, but we may be able to add value by extending the ontology to allow reasoning based on geographic region, industry categories, etc. The 1998 CD-ROM (most recent available from GPO) includes the source document in SGML (library/books/fb98/fb98.sgm). Countries begin with <geodesc> tags. Facts are recorded as <field> <data> pairs. An HTML representation of the World Fact Book is available at http://www.cia.gov/cia/publications/factbook/. PARKA triples encoding facts (in several ways) are available at http://www.cs.umd.edu/projects/plus/Parka/parka-kbs.html. Deb McGuiness has a World Fact Book ontology in Ontolingua. The CIA World Fact Book itself is in the public domain. No Intellectual Property issues. Encode the resumes of a company's employees and job applicants in DAML. Temporal ranges for employee-of relations. Using DAML for historical records. Synonymy, as company names change over time. What existing employees may have worked with an interview candidate in the past? (based on matching company/dates and optionally city) What employees have worked with both knowledge representation and Java? Imagine if the Wall Street Journal were published every day using DAML as well as text. The ability to mix and relate structured and unstructured content. Ideally, the DAML facts would contain references to the underlying text from the article. Reification (DAML assertions are "as reported by the Wall Street Journal"). Temporal data (articles are dated). Various corpora (including the Wall Street Journal) are available from the Linguistic Data Consortium at http://www.ldc.upenn.edu/. Notify me with normal priority whenever a story appears about my company is mentioned. Notify me with high priority whenever such a story portrays my company in a bad light. Notify me whenever one of my competitors is mentioned (e.g. based on Standard Industrial Classification code). We could potentially use another newspaper source, but the narrower domain focus and recognition of the WSJ are attractive. This was demonstrated by BBN, using New York Times articles from the MUC-7 conference, at the DAML Kickoff Meeting in August 2000. Use DAML to encode the information stored by the Center for Army Lessons Learned. Some information is publically available at http://call.army.mil. CALL officials have already expressed interest in DAML, and attended the DAML Kickoff meeting. Various personal financial information is now available via the WWW (bank accounts, stock portfolios, mutual funds, retirement funds, credit card balances, etc.). It would be possible to write an agent that polled these sources daily to track one's "InterNet Worth" (assets - liabilities based on Internet-accessible data sources), but this would currently require a considerable amount of code customized for each site. How much easier would it be to develop such an agent if all of this information were published using DAML? Increased development efficiency (reduction in source lines of code required to build agents) afforded by DAML. Security and privacy issues. Encoding efficiency afforded by DAML. Agents don't read ads! What's my instantaneous net worth? Most major financial institutions now make account information available via the Internet (in ad hoc, proprietary formats). Mike Dean, 28 Sep 2000: Teknowledge's TekPortal Financial Data Aggregation (http://www.teknowledge.com/eCommerce/tekportal.htm) does just this, using the XML-based Open Financial Exchange (EFX) protocol or custom HTML screen scraping. The W3C DAML proposal is available at http://www.w3.org/2000/01/sw/DevelopmentProposal. It includes a number of ideas for applying DAML to the daily operation of the World Wide Web Consortium. In particular, it suggests (in sections C and D) the use of SWeLL to specify and check access control policies for www.w3.org. Logical inference Security Proof checking The Mozilla Open Directory (dmoz) effort is building a standard taxonomy of WWW sites similar to that used by Yahoo, Netscape, etc. Many of the major portals have already adopted Open Directory. The ability to handle a very large, though simple, ontology. The Open Directory structure and contents are available in RDF form from http://dmoz.org/rdf.html. Web-in-a-Box is a new DARPA ITO program under Jean Scholtz that seeks to provide cached versions of WWW pages that have been identified as particularly relevant by staff at operational military commands. It would be desirable to include DAML content as part of this material. Mike Sullivan and other BBN staff involved in a Web-in-a-Box jumpstart effort are currently surveying operational sites to identify high priority unclassified WWW sources. The Web-in-a-Box BAA00-41 was just cancelled. The U.S. Security and Exchange Commission's EDGAR database of filings for publically-traded companies have long been available on the Internet. The submission are semi-structured SGML with lots of large text blocks. The submissions contain a wealth of timely information about financial performance, corporate officers, subsidiary relationships, competition, etc. Digital signing of DAML assertions (the EDGAR submissions are already signed, although these signatures wouldn't match for transformed data). ontology translation. An EDGAR ontology is likely to be similar to, but perhaps different from, a Wall Street Journal ontology. This could present an opportunity for ontology translation (and/or sharing) in a restricted yet compelling domain. See http://www.sec.gov/edgarhp.htm. The EDGAR data is in the public domain. ... suggested by Stefan Decker Use DAML and DAML-S to encode the tactics, techniques and procedures for joint and coalition search and rescue missions. The ability to encode process and agent related information in a form that can be used to provide task support and reasoning. http://www.dtic.mil/doctrine/jel/new_pubs/3_50_21.pdf ]]> http://www.aiai.ed.ac.uk/project/cosar-ts/ ]]> CoSAR-TS project is to investigate the use of DAML and DAML-S for SAR. ]]>
