LTM – Cheat-Sheet Subject Indicators (Zero Or More)

LTM – Cheat-sheet Subject Indicators (zero or more) Ontopia developed Linear Topic Map notation @”URL” (LTM) as a text format for topic maps. Its brevity eases hand authoring of topic maps. (Line returns, Subject Locator (only one) tabs, etc., are used for presentation below. Single spaces have the same meaning.) %”URL” Topics Occurrences Minimal topic – ID between square [ ] brackets. {ID of topic with occurrence, Base/Sort/Display Names ID of occurrence role type, [ID = “basename”; [and] “sortname”; “displayname”] “locator of occurrence”} / scope [optional] To skip sortname, use ;; to signal its missing. or Repeat base/sort/display cluster for a topic: [[resource data inline]]} / scope [optional] = “basename”; Associations “sortname”; “displayname”] type(player : role[opt], player : role [opt]) Scope on Names Scope associations, following “)” with “/ scope” Names are scoped with “/ “ , followed by a topic If no roles, defaults to topic type. Topic definition, ID. […], can appear as player. [ID = “basename” / scope Reification … ] Names A single “/” operator scopes the base/sort/display name group. [ID = “basename” ~ topicid ….] Variant Names [ID = “basename” / scope ~ topicid ….] Appear after displayname (if any). Occurrences (“variant” / scope) {topicid, type, locator/resource data} ~ topicid Variant names always have scope.

A 3-Tier Application for Topic Map Technology
Proceedings of the 6th WSEAS International Conference on Applied Computer Science, Tenerife, Canary Islands, Spain, December 16-18, 2006 356 A 3-tier Application for Topic Map Technology A. PAPASTERGIOU, G. GRAMMATIKOPOULOS*, A. HATZIGAIDAS, G. TRYFON Department of Electronics, (*) Department of Esthetics Alexander Technological Educational Institute of Thessaloniki, EPEAEK II Sindos, 57400, Thessaloniki, Macedonia, GREECE Abstract: In the context of this paper the design and construction of a 3-tier application system for topic map technology is presented in detail. The proposed system employs Enterprise Topic Map Server (ETMS) that manages topic maps (TM) and establishes communication with client applications and persistent database. Yellow Web Services have been customized in order to achieve communication issues and exchange of TM. A client application is addressed to TM developers for editing and visualization of TM. Furthermore, the definition of TM Schema as well as the possibility to process rules and queries are supported. Another key aspect of the present paper is to analyze how different technologies utilized to formulate such a system. Key-words: Topic map, Server, Web services, Client, 3-tier, TM schema, Retrieval 1 Introduction definition of TM Schema as well as the possibility to The Topic Map model describes a mechanism for process rules and queries are also supported. In the representing knowledge about the structure of next sections the overall architecture of the proposed information and organizing it into topics [1,19]. Topics system as well as technologies that are implied in have occurrences and associations that define order to build the system are represented in details. relationships between the topics, creating thus a semantic network over the information [8,18].

Mapping Topic Maps to Common Logic
MAPPING TOPIC MAPS TO COMMON LOGIC Tamas´ DEMIAN´ Advisor: Andras´ PATARICZA I. Introduction This work is a case study for the mapping of a particular formal language (Topic Map[1] (TM)) to Common Logic[2] (CL). CL was intended to be a uniform platform ensuring a seamless syntactic and semantic integration of knowledge represented in different formal languages. CL is based on first-order logic (FOL) with a precise model-theoretic semantic. The exact target language is Common Logic Interchange Format (CLIF), the most common dialect of CL. Both CL and TM are ISO standards and their metamodels are included in the Object Definition Metamodel[3] (ODM). ODM was intended to serve as foundation of Model Driven Architecture (MDA) offering formal basis for representation, management, interoperability, and semantics. The paper aims at the evaluation of the use of CL as a fusion platform on the example of TM. II. The Topic Maps TM is a technology for modelling knowledge and connecting this structured knowledge to relevant information sources. A central operation in TMs is merging, aiming at the elimination of redundant TM constructs. TopicMapConstruct is the top-level abstract class in the TM metamodel (Fig. 1). The later detailed ReifiableConstruct, TypeAble and ScopeAble classes are also abstract. The remaining classes are pairwise disjoint. Figure 1: The class hierarchy and the relation and attribute names of the TM metamodel. TopicMap is a set of topics and associations. Topic is a symbol used within a TM to represent exactly one subject, in order to allow statements to be made about that subject.

Semantic Mapping in ROS XAVIER GALLART DEL BURGO
Semantic Mapping in ROS XAVIER GALLART DEL BURGO Master’s Thesis at CVAP/CAS, The Royal Institute of Technology, Stockholm, Sweden Supervisor: Dr. Andrzej Pronobis Examiner: Prof. Danica Kragic August, 2013 Abstract In the last few years robots are becoming more popular in our daily lives. We can see them guiding people in museums, helping surgeons in hospitals and autonomously cleaning houses. With the aim of enabling robots to cooperate with humans and to perform human-like tasks we need to provide them with the capability of understanding human envi- ronments and representing the extracted knowledge in such a way that humans can interpret. Semantic mapping can be deﬁned as the process of building a representation of the environment, incorporating semantic knowledge obtained from sensory information. Semantic properties can be extracted from various sources such as objects, topology of the envi- ronment, size and shape of rooms and room appearance. This thesis proposes an implementation of semantic mapping for mo- bile robots which is integrated in a framework called Robot Operat- ing System (ROS). The system extracts spatial properties like rooms, objects and topological information and combines them with common- sense knowledge into a probabilistic framework which is capable of in- ferring room categories. The system is tested in simulations and in real-world scenarios and the results show how the system explores an unknown environment, creates an accurate map, detects objects, infers room categories and represents the results in a map where each room is labelled according to its functionality. Acknowledgements First and foremost, I would like to express my gratitude to my super- visor, Andrzej Pronobis, for giving me the opportunity to develop my thesis in one of my passions, the robots.

(August 2011) Rhonda Thayer Dunn, B.S., Xavier University of Louisiana; M.C.S., Howard University; M.U.P., Texas A&M University Chair of Advisory Committee: Dr. John J. Leggett A griotte in West African culture is a female professional storyteller, responsible for preserving a tribe‘s history and genealogy by relaying its folklore in oral and musical recitations. Similarly, Griotte is an interdisciplinary project that seeks to foster collaboration between tradition bearers, subject experts, and computer specialists in an effort to build high quality digital oral history collections. To accomplish this objective, this project preserves the primary strength of oral history, namely its ability to disclose ―our‖ intangible culture, and addresses its primary criticism, namely its dubious reliability due to reliance on human memory and integrity.

TMRA 2010 is the sixth conference in this annual series of international conferences dedicated to Topic Maps in science and industry. The motto of the TMRA 2009 conference, “Linked Topic Maps”, was about spinning a global web of interchangeable and linkable topic maps. Linked Topic Maps was about lightweight semantic integration and fusion of heterogeneous sources of structured and unstructured data, based on the integration model provided by Topic Maps.
