Pre-Context Semantic Web

• open to read/write ontology has failed 12 14

• most tools today are closed worlds with APIs -- like LinkedData 13

• a large variety of tools for working with closed ontologies 11

Facets

• facets are basically personalization of ontology 04 05 06

• much research focused on user modeling for personalization 07

• the ultimate goal is faceted search1. each node in ongology graph hasmultiple contexts2. on top of search people are offered browsing function 08

• many existing faceted search portals 09 10

Two Ways to Approach Context

1. Context: Definition 1 (facets)◦ one item -- a node in ontology -- andmany contexts (facets)◦ facets are filters in search◦ you need as many queries as you have items

2. Context: Definition 2 (proposed)◦ multiple items and multiple nodes◦ context is a topology overlaying multiple nodes◦ discover new nodes and items by browsing the topology

... is a design for a context-aware ontology-based search functionplus a metadata management solution which uses Metro Maps as thefundamental underlying structure

• Metromap itself is not a new concept 02

• already used in practice -- software projects, group activities, etc. 03

• why the name: something you have seek-ed + sounds similar to trainsof thought -- perfectly describes the intentions

... is a topology in which there are stations and lines where the lattercan overlap at individual items of the former.

• MetroMaps are not MindMaps! 02

• ... we use metromaps everyday -- train maps of cities in Japan

• metromaps are helpful in many -- completely unrelated -- areas of application 03

• feature-not-a-bug: one map is a whole -- inseparable -- unit

Facets vs Metromaps

Facets vs Metromaps: Tags

• FEW: search or browsing produce relatively few results -- human consumption

• BROWSABLE: is metadata browsable?

• SCALABLE: same design for small and large bodies of content, groups,etc.?

• OWNABLE: metadata owned by user? -- or out of users' reach?

• TEAMABLE: can be shared by several members of a team? -- has to beownable, of course

• EVOLVABLE: whether your personal metadata can evolve in time -- along-term recommendation service

• ....

ToS: Unique Features

1. ToS is a human-oriented service

2. facets: search then browse,ToS: search and/or browse3. ToS is owned and managed by the user

◦ the service is a helper, not a dictator

Nicecover: The Story

• idea first presented atLOIS back in September

• why: i-Scover was a major disappointment -- in terms of context, API,social features, etc.

• the main intention: create a socially distributed/managedmetadata on top of any major scientific portal◦ I use (have used) it for metadata which I shared with graduate students

Nicecover as a ToS Service

• Nicecover Data: distributed metadata created by users -- distributedscattered metromaps

• Nicecover as ToS:1. aggregation and merges

2. recommendation service3. on-demand metromaps -- example: who's working on ontologicalcontext search?
