要約: A text retrieval method called the thematic geographical search method has been developed and applied to a Japanese encyclopedia called the World Encyclopedia. In this method, the user specifies a search theme using free words, then obtains a sorted list of excerpts and references to encyclopedia sentences that contain geographical names. Using this list, the user can open maps that indicate the location of the names. To generate an index of names for this searching, a method of geographical name extraction has been developed. In this method, geographical names are extracted, matched to names in a geographical name database, and identified. Geographical names, however, often have several types of ambiguities. Ambiguities are resolved using context analysis and several other techniques. As a result, the precision of extracted names is more than 96% on average. This method depends on features of the Japanese language, but the strategy and most of the techniques can be applied to texts in English or other languages.

要約: This document describes a QoS PIF MIB (Quality-of-Service Programming-Interface Management-Information-Base) to be used as an SNMP-based programming interface for routers. This MIB is intended to be a programming interface for router QoS functions, especially DiffServ-related [RFC2475] functions including packet scheduling (queuing), dropping, and metering that must be modular and concisely described. Traffic-conditioning rules and metering rules for DiffServ-related functions are defined modularly by using "virtual flow labels" and exclusive conditions in rules, and new classifications for packet-scheduling and packet-dropping functions are introduced. This document focuses on satisfying the requirements on programming interfaces or programming languages for router control. Thus, the focus is different from that of DiffServ MIB [DSMIB] or QoS PIB [QoSPIB].
