Applying Semantic Web in Competence Management

Abstract: Efficient competence management is essential in knowledge-based companies. This chapter describes how the Semantic Web technologies can be used in managing employee competencies. Applying the Semantic Web technologies in competence management enables building systems that support highly dynamic environments, are extensible as well as interoperable between different application domains, and benefit from the use of machine-accessible semantics. Competence management systems should be available not only for managers but for all the employees of the company. As companies get larger, it becomes increasingly difficult to manage the knowledge and competencies that their employees have. Utilizing the Semantic Web opens many possibilities for building flexible systems for competence management. INTRODUCTION

Surveillance of NTP-servers in customer's network

Abstract: During the last three years, the NTP servers hosted by the largest Telecommunications and Internet Service Provider in Sweden have been monitored and logged with traceability to UTC(SP), including an estimated uncertainty calculated from the measurements, stratum-level, and synchronization source. The surveillance is ongoing and provides updated information on NTP-synchronization status and network congestions.

Robust parsing and spoken negotiative dialogue with databases

Abstract: This paper presents a robust parsing algorithm and semantic formalism for the interpretation of utterances in spoken negotiative dialogue with databases. The algorithm works in two passes: a domain-specific pattern-matching phase and a domain-independent semantic analysis phase. Robustness is achieved by limiting the set of representable utterance types to an empirically motivated subclass which is more expressive than propositional slot–value lists, but much less expressive than first-order logic. Our evaluation shows that in actual practice the vast majority of utterances that occur can be handled, and that the parsing algorithm is highly efficient and accurate.

Resource control in a wireless communication network

Abstract: A wireless access network comprises dedicated data channels and at least one shared data channel in at least one cell. At least part of the mobile stations in the cell are capable of communicating alternatively on a dedicated data channel or a common shared data channel. A target bit rate is provided as a minimum bit rate that should be achieved in the common shared data channel by each user. If this bit rate is not achieved by a user, it is checked whether the dedicated data channel resources could offer a better bit rate level for the user. If this is the case, a dedicated data channel connection is established for the user although the user's mobile station is capable of operating in the common shared data channel.

Improved solution for connectivity

Abstract: A communication system that comprises a mobile station (17), an access point (10, 11), and a wireless interface for implementing a local connection between the mobile station and the access point. The mobile station (17) is configured with a virtual device that a virtual device that provides a serial port emulation for a terminal function and interfaces the serial port emulation with an Ethernet-based connection. simple user experience of serial connection type applications may be provided within a wider region of coverage. A user may use the familiar applications in a consistent way without worrying about the creation of IP connection or basically even needing to know which kind of radio units his or her user equipment comprises.
