Self-introductionSelf-introductionI have been researching and developing distributed Location-Based

Services and Mapping Systems for WWW at KDDI since 1995. KDDI:Telecommunication Career of Japan

Its principles:• Based on map visualization (rather than geo-spatial semantics)• Visual inter-operation (the “Hyper-layering” pat. US:6107961, JP:3503397)

• Target is commodity rather than mission critical.• Target is the infrastructure rather than differentiated service.

Standardization at W3C SVG1.1Standardization at W3C SVG1.1

• Top 2 of SVG1.1 Mobile Usage Scenarios : 2001– Location-Based Services.– Mapping and Positioning.

• SVG1.1 Recommendation : 2003– Royalty-free use of "Hyper-Layering" was guaranteed as long as it

used with SVG for it was adopted by SVG1.1 specification.

BUT!At present, distributed web mapping platform as the social

infrastructure that the author imagined has not been completed.

Only proprietary Location Based Services begins to be acknowledged by the public.2003 : LBS for cellular phone with GPS (ezNaviWalk)2005 : Google Maps for PC

Effectiveness of open and inter-operable LBS is still to be demonstrated and hard to inform to the public.


Findings from the experienceFindings from the experience

• Proprietary Location-Based Services technology overcame the chasm in 2003.

• But, it takes longer to construct the standardized platform compared with the construction of proprietary services. That is, chasm period of the public infrastructure is very long.

• A persistent long-term activity is necessary for constructing the standardized information platform.


Importance of Human-understandabilityImportance of Human-understandability

• It is related to the easiness of the acquisition of information literacy (accessibility in the wide sense).

• Information which only the machine can understand is convenient for the ICT vendor to dominate market. That is, it promotes lock-in situation for ICT vendors.

(Lock-in by ICT knowledge)• XML Schema, *ML and WS* boom in 2000 might have been based

on this. And, did it succeed? No!• Web2.0 might be starting afresh the Semantic web, but it requires

human understandable web. It is establishing a minimum vocabulary for the metadata of human understandable contents. (DC, RSS..)

• However, the current Web2.0 campaign by ICT vendor resembles closely the situation in 2000.


Wave of WWW with cycle of ten yearsWave of WWW with cycle of ten years

• They try to “Lock-In" by using the expectation by the boom of WWW.

• When the expectation exceeds the limit of an actual interoperation ability, WWW becomes the concentrated and tight coupling system, and the charm of WWW declines. WWW disappoints people and the development stalls. Expectation

Findings from the experienceFindings from the experience

• It is the necessary condition of WWW to secure human understandability.

• It resembles human's "Language" problem that Mr.Murata pointed out, too.

• And, the language dependency of the map is low
