MOTIVATING CONTEXT SEMANTIC SPREADING ACTIVATION PERSPECTIVES


Motivating context

Popular social platforms are now massive,

and highly heterogeneous


“ Social object is the reason why people affiliate

with each specific other and not just anyone.”

Semantic spreading activation

• Why semantic spreading activation ?

- Spreading activation [Collins and Loftus, 1975] was designed to be

applied on associative networks

- It was successfully applied in a lot of recommender systems eg.

[Kovac and Ueno, 2006]

- It showed very interesting performance on huge datasets

[LarKC,2008]

- Integration of semantics in spreading activation process showed

very encouraging results [Rocha and al., 2004]

Perspectives

• Use underlying schemas to compute an advanced semantic

distance measure between nodes

Semantic distance ? [Corby and al, 2008]


Perspectives

• Exploitation of social interactions in the recommandation

process

Louvre social page

E. Delacroix social page

Users interactions similarity ?

…Delacroix…

…Delacroix…

…Louvre…

…Louvre…


Conclusion

• Synergies between social and semantic web open new

research perspectives and semantics can help to make sense

from social networks data.

• First tests show encouraging results for semantic spreading

activation and multiple improvements are possible

• Interactions centered around social objects are high valued

for recommendation process and can make it dynamic
