This paper will introduce a number of predefined elements for the topic mas data model. The paper will start with a short introduction of the level and possible context of these elements. Then the problem the elements proposed here are supposed to solve will be described. This will be the problem of adding temporal qualifications to a topic map. A set of criteria for the quality of a possible solution will be given and possible solutions will be evaluated against these criteria. This will lead to the final proposal for adding temporal qualification to a topic map.

    Temporal Qualification in Topic Maps Temporal Qualification in Topic Maps Presentation Transcript

    • Introduction Create a Standard? Goals Solution Temporal Qualification in Topic Maps Lutz Maicher and Christoph Teichmann Topic Maps Lab Leipzig IMPRS Neurocom Leipzig 12. November 2009 Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution 1 Introduction Predefined Constructions Temporal Qualification 2 Create a Standard? 3 Goals 4 Solution Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Predefined Constructions Goals Predefined Constructions Solution Predefined Constructions: automatic construction of topic maps reasoning with topic maps faster design of topic maps optimization of topic maps user interfaces Example: supertype-subtype Relation Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Predefined Constructions Goals Predefined Constructions Solution Defined by: mapping from Data to constructions predefined PSIs for the types Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Predefined Constructions Goals Predefined Constructions Solution Example Problem: Temporal Qualifications Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Predefined Constructions Goals Predefined Constructions Solution What is included by this type of information: all connections to the temporal domain should include information about referents and topic map constructs also interesting: validity information should cover all Topic Map constructs Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution Why a standard for this problem is necessary: Temporal Qualification is common quite natural for reasoning and ordering information can often be extracted automatically Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution Why one standard for all Problems? similar information is in similar ’places’ conceptual simplicity easy to learn for Topic Map Designers least assumptions about the Topic Map Data Model Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution What should a good Standard do? minimal with respect to new PSIs introduced minimal with respect to constructions needed to create an instance Temporal Domain should be modeled with Topics should be possible to add temporal information to any construct multiple temporal qualifications should be possible information about temporal information should be possible no extensions to the Topic Maps Data Model allowed Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution Our Proposal: create topics for temporal information create associations of appropriate type to connect time to topics use reifier for all other constructs Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution Example: John; http://www.foo.bar/John; - "John Johnson"; AccountNumber:’1234567’ – Reifier: Reifier1. lived(person:John,birth:01.02.1904,death:05.06.1977). Reifier; http://www.foo.bar/Reifier1. collected_at(collected:Reifier,collection_time:08.09.1967). Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution not the simplest approach with respect to locators or constructions meets all other criteria types of information can be distinguished by supertype-subtype relation Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution 1 The subtypes of the topic that has pred/meta-temporal-qualification as its subject identifier should be the types of those associations that represent temporal meta information. 2 The subtypes of the topic that has pred/domain-temporal-qualification as its subject identifier should be the types of those associations that represent domain related temporal information. 3 The subtypes of the topic that has pred/validity-temporal-qualification as its subject identifier should be the types of those associations that represent temporal information about validity. Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution 1 roles of some subtype of the topic that has pred/Timed as its subject identifier should be the roles of topics that represent elements to which a temporal qualification should be added. There is no restriction to the type of players for these roles. 2 roles of some subtype of the topic that has pred/Time as its subject identifier should be the roles of topics that represent the date which is used in a temporal qualification. These roles should only be played by topics that represent temporal information. Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
    • Introduction Create a Standard? Goals Solution discussed the idea of predefined constructions for Topic Maps one example: temporal qualification proposed solution: association with topics representing temporal information and the use of reifier Lutz Maicher and Christoph Teichmann Temporal Qualification in Topic Maps
