Search terms are like keys to documents or to any other type of content. In our days, not only the volume of available documents is increasing rapidly, but also the size of the keychain is growing.
Before we start to discuss how to organize/index the documents themselves, we should first talk about methods to organize the keys.
Take a look at these three approaches:
On the left-hand side you can see a nice example of implicit semantics. The old receptionist knows exactly which key fits into which lock. This knowledge is implicit and can be remembered by the shapes of the keys. Before the old receptionist has retired and the knowledge would have gone, labels have been attached to every key. The semantics of the keys has become more explicit, but this is still quite ambiguous (as visualised in the center column). There is no index of all the labels and colours being used, neither an explicit methodology how new keys should be labeled. As the hotel grows, the labeling system becomes quickly a mess. On the right-hand side the solution for this problem is offered: Not only the semantics of the keys becomes more explicit, but also the semantics of the semantics. For instance, the position of a key represents the position of the room, which can be unlocked by this. The number of the row of the key cabinet represents the storey of the room being unlocked, etc.
This methodology in order to organise keys helps to orientate and to remember; it can be explained with low effort to any new receptionist and it can be scaled-up in case your hotel should grow in the next few years.
Most information professionals already know: separation of content and presentation helps to manage and deliver complex information. This can only be done by using enriched structured content. Some call this intelligent content.
But why exactly is metadata per document (some call it “tagging”) not enough?
Here is a very brief slide-deck, which explains the difference between the traditional approach and the graph-based approach to develop not only a metadata layer seperated from the content layer, but also a knowledge layer on top of it.
Why semantic knowledge graphs matter
SEMANTiCS conference celebrated its 10th anniversary this September in Leipzig. And this year’s venue has been capable of opening a new age for the Semantic Web in Europe – a marketplace for the next generation of semantic technologies was born.
SKOS is at the intersection of three disciplines and their paradigms:
Whilst librarians, taxonomists, and specialists in the fields of text mining and entity extraction have started to embrace SKOS, especially ‘ontologists’ from artificial intelligence community still remain sceptical about the capabilities of SKOS.
With the latest release of PoolParty Thesaurus Server a full-blown ontology management facility has been introduced which can now be used to extend expressivity of SKOS knowledge models. For instance, SKOS concepts can become any other type of resource and by that schemas of additional relations and attributes can be applied to the concept.
PoolParty’s philosophy is to support users with Simple Knowledge Organization Systems (SKOS) first, to let them grow instantly by using various mechanisms like ontologies, text corpus analysis or linked data enrichment. All of them can nicely be combined. Users benefit from a step to step approach, not being bothered by an overarching approach from the very initial step. Learn more >>>
SEMANTiCS conference series will celebrate its 10th anniversary this year in September. SEMANTiCS (formerly known as I-Semantics) has had a long tradition in buidling bridges between practitioners and researchers in the areas of semantic web and linked data technologies. Therefore the SEMANTiCS consortium has developed new strucutures to further elaborate on this special character of this event series:
- Each conference session will combine talks from industry and research – those two interest groups won’t be seperated from each other anymore
- DBpedia community will be integrated deeply into SEMANTiCS conference: DBpedia has been the most successful activity in this area so far. A lot of industry-related projects has been built around this dataset. Therefore the 2nd meeting of the DBpedia association will be co-located with SEMANTiCS (taking place on September 3rd, also in Leipzig).
- Transfer-oriented side events and a centrally located market place will offer great opportunities to discuss about state-of-the-art technologies in the areas of Semantic Web standards based software and products.
I am also happy to announce that PoolParty Semantic Suite is one of the Gold sponsors of this event this year. See you in Leipzig!
