FOAF – Friend of a Friend

FOAF – Friend of a Friend


The FOAF (“Friend of a Friend”) project is a community driven effort to define an RDF vocabulary for expressing metadata about people, and their interests, relationships and activities. Founded by Dan Brickley and Libby Miller, FOAF is an open community-lead initiative which is tackling head-on the wider Semantic Web goal of creating a machine processable web of data. FOAF facilitates the creation of the Semantic Web equivalent of the archetypal personal homepage: My name is Leigh, this is a picture of me, I’m interested in XML, and here are some links to my friends. And just like the HTML version, FOAF documents can be linked together to form a web of data, with well-defined semantics.

A Person with their Nearest Airport

Below is an example which describes the nearest airport to a person called Libby Miller. It links to the person’s workplace’s homepage and their project homepage, and an interest – the Semantic Web. It uses the foaf (friend of a friend) namespace among others. Using nearestAirport is a simple way of identifying a person’s locality without being too specific. more…

Soccer example

This user profile example above, with different cognitive characteristics of the same topic, represents the person John Wayne, who has tree different cognitive patterns – a skill (cco:skill), an expertise (cco:expertise) and an interest (cco:interest) – with the topic soccer. At the beginning, each semantic relation is modelled as shortcut relation. Afterwards, follow more detailed descriptions of these three cognitive characteristics, which are associated to John Wayne by using the property cco:habit. Each of these cco:CogntiveCharacteristic instances include, besides the basis information of the shortcut relations, also a weight description and two of them, furthermore, an activity relation (associated by cco:activity). So that a reasoning engine is now not only able to automatically infer the knowledge from the shortcut relations now, but rather then also from the reification class instances. That means, one can conclude that John Wayne * can play soccer quite moderate, * has a quite good knowledge about the topic soccer and * and is moderatly interested in watching soccer. Such a modelling has the advantage that one can talk about one and the same topic, independently of the activities that are related to cognitive pattern descriptions of a person. This is possible, because activity, cognitive characteristic and topic have their own, separate dimension. Due to the property reification definitions from here and the shortcut relation and property reification rules of the Property Reification Vocabulary one can clearly reason that the shortcut relations and reification class instances in the soccer example above are belonging semantically together (here pairwise). more…

Using based near

The foaf:based_near relationship links a “spatial thing” (anything that can be somewhere) to a point in space, typically specified using the geo:lat / geo:long geo-positioning vocabulary (see GeoInfo in the W3C semweb wiki for details). Note that this same markup could be applied to other spatial things, such as shops, artifacts etc. more…

EXIF For a Digital Image Including External Conditions

This vocabulary takes advantage of Exif’s IFD (Image File Directory) to express structured data description. While TIFF 6.0 attribute tags can be regarded as properties of image itself, many of Exif-specific attributes such as flash or fNumber are properties of picture taking condition, and GPS attributes are properties of a location. This vocabulary maps Exif directories to corresponding ‘Image File Data’ classes, and describes those class instances using properties in the IFD. Some tags have integer values whose interpretation are defined in the spec. In this vocabulary, those values are treated as controlled value resource, e.g. ‘#top-left’ instead of integer value ‘1’ for ‘orientation’ tag. more…

Simple Music Artist Recommendation

This example is a simplified one from the extended music artist recommendation example above. It is simply stripped down to its high level recommendation. The target, where the recommendation is for, is now related by the inverse property of rec:recommendation, rec:for. Furthermore, it includes a fictional audience group (ex:FunkyPeople), which is related by the property rec:recommendation_audience. Finally, the recommendation objects are now simply related by the property rec:recommendation_object. Of course, this doesn’t include the ranking, it is now an unordered list. However, it still includes the relation to its similarity method (ex:lfmTrackSimilarity). more…

UMIRL example

This example was originally modelled with help of UMIRL (http://www.media.mit.edu/~chaiwei/papers/usermodeling.pdf) and is now recreated with the Cognitive Characteristics Ontology. This example shows a part of an user profile as it can be taken from an user account of a personal music knowledge base. The user profile is from the person John White, who can play the piano and sing by having no education in music. Furthermore, he is interested in several music genres, the music artist Wolfgang Amadeus Mozart, the music group the Beatles, the music song “Yesterday” from the Beatles and some self-defined idiosyncratic music genres. At the beginning, all cognitive patterns of this user are described by simple semantic relations, which are sub properties of cco:cognitive_characteristic. Thereby, the most of the topics of the cognitive characteristic relations are information resources from the information service DBPedia and one topic is a information resource from DBTune. Afterwards, some of these shortcut relations are described more in detail with help of cco:CognitiveCharacteristic instances. Each of these cognitive characteristic descriptions is related to a weighting with a different weight value (related by wo:weight_value) and the same scale (related by wo:scale). Due to these weightings, we can conclude that John White can sing and play the piano quite good. However, he has no knowledge in musical foundations. Furthermore, a cco:CognitiveCharacteristic instance is associated with a topic (by cco:topic) of a shortcut relation and a property (by cco:characteristic) of such a relation. Besides these information some of them are also related with an activity (associated by cco:activity), which are information resources from OpenCyc (playing a musical instrument) or DBPedia (singing). This user profile example includes especially detailed descriptions of John White’s interest in specific music genres. Thereby, we can conclude (besides other things) that he is a big fan of Blues and Rock music and quite interested in romantic music (ex:IdiosyncraticGenre2). The last music genre is defined as music context, which he prefers weekdays (represented by days:WeekdayInterval) at “bedtime” (ca. 11 pm). This idiosyncratic genre is itself defined as a sim:Association instance, which is titled as “romantic music” and should be very slow (largo, associated by ex:tempo as sub property of ao:context). more…

Scientific Research Interests Example

This example is originally taken from the E-foaf:interest Vocabulary Specification 0.2 (http://wiki.larkc.eu/e-foaf:interest) and was transformed to be conform with the current version of the Cognitive Characteristics Ontology. This example describes a person (here Ricardo Baeza-Yates), who is interested in (foaf:topic_interest) a specific topic (here “The World Wide Web”). This interest is described more in detail with help of a cco:CognitiveCharacteristic instance (ex:WebInterest). It has a current weight (wo:weight), a total weight (cco:overall_weight) and two attention durations – a ultimative duration (cco:ultimative_duratation) and a longest duration (cco:longest_duration). All these values can be timestamped, e.g. re. their date of modification (dcterms:modifified). A cco:CognitiveCharacteristic instance (ex:ASpecificConcext) describes the appearing of this interest in a certain context (here a specific paper). To describe the different weightings, different scales can be associated to them. more…

Cognitive Patterns Example

This example shows a part of a cognitive pattern model of a person (here Bob Ferris). It consists of an example for each specific competence (cco:competence) property (cco:skill, cco:expertise and cco:belief) and an interest (cco:interest). Each topic of the interest, skill and expertise is a specific DBPedia category. The topic of the belief is represented by a DBPedia Live entry. Based on the SKOS organized taxonomy of the DBPedia categories, one can infer their contexts and will realized that all mentioned topics etc. are somehow related to each other. At first, an upper category of dbpedia-cat:Semantic_Web and dbpedia-cat:Ontology_(information_science) is dbpedia-cat:Knowledge_representation, which is related by the property skos:broader. However, a further upper category of dbpedia-cat:Ontology_(information_science) is dbpedia-cat:Ontology. Finally, the entry dbpedia-live:Named_graph is tagged with dbpedia-cat:Semantic_Web and the entry dbpedia:Knowledge_engineering is tagged with dbpedia-cat:Ontology_(information_science). So these relations can illustrate a coherence of cognitive patterns of a person. Thereby, the modelling of the cognitive characteristics descriptions (cco:CognitiveCharacteristic instances) of a person, especially weightings and characteristic dynamics can be described in the same manner. To summarize the description above one can say: Bob Ferris is interested in Knowledge Representation, has some expertise in Ontologies, some skills in handling (Knowledge Engineering) Ontologies in the topic of Information Science and a certain belief in the Named Graphs approach. more…

Preference Example

This example is originally taken from the first draft of the Weighted Interest Vocabulary (http://xmlns.notu.be/wi/) and was transformed to be conform with the current version of the Cognitive Characteristics Ontology. This example shows a part of a preference model of a person (here Libby Miller). It consists of two preferences, each is modeled as a cco:CognitiveCharacteristic instance, which are related to the person by using the property cco:habit. An interest itself consists here at least of a topic (cco:topic), a weight (wo:weight) and an characteristic dynamics description (cco:characteristic_dynamics) relation. Furthermore, in addition to the standard weight relation (wo:weight), which should reflect the current interest in a topic, the overall interest in a topic, can be related by using the property (cco:overall_weight) with a cco:CognitiveCharacteristic instance as subject. The topics of the weights are both a BBC radio program. Every weight is modeled as a wo:Weight instance, which consists here of the weight value (wo:weight_value) and a link to a scale description (wo:Scale). A wo:Scale instance describes the range (wo:min_weight and wo:max_weight) for the groups of weights, which are linked to it, and furthermore, the step size (wo:step_size), which is possible in this range. cco:CognitiveCharacteristic instances can have different interest dynamics (cco:CharacteristicDynamics) relations. These are specific events (event:Event), which model temporal interest statistics. Besides the already known time period (days:WeekdayInterval), which is related by the property cco:appear_time, a temporal weight (related by wo:weight_value, because cco:CharacteristicDynamics is a sub class of wo:Weight) and can describe the temporal interest in a topic to a context, which is here additionally described by a spatial relation (event:place). To sum up the example, the person Libby Miller prefers radio 4 over radio 5 when she is working at her working place (which is every weekday between 8am and 7pm). more…

				<dc:description>These shows are really just two sides of the same coin. Though the hosts pretend to have a long-standing rivalry due to differing political views, their friendship is noticeable, and the differing political views mostly imaginary. Many members of the original Daily Show production moved across the street to the set of The Colbert Report to bring the same production qualities and style to the newer show. Colbert has proven the more aggressive but Stewart still holds his own and subtly gets the best of Colbert (as per the script... but hey, I love it anyway as long as their exchanges are worth a laugh).</dc:description>

Music Preferences Example

This example describes a person (here Bob Ferris), who is interested (cco:interest) in some music artists (James Brown and Jeff Mills) and does not like (cco:not_interested_in) some music genres (Schlager and German Folk Music). Besides, the detailed interests descriptions (cco:CognitiveCharacteristic) with a characteristical common appear time (cco:appear_time), further characteristic dynamics (cco:CharacteristicDynamics) with separate weightings are added to them, e.g. a description of a specific Techno party (ex:TechnoParty), where Jeff Mills played, with a specific location (related by event:place), an event description (related by dcterms:subject), and a period of time, where Bob was a big fan of him (ex:BigFan). more…
