Knowledge of the web

Knowledge of the Web

  • String searching does not always convey the true meaning of content.

  • Search by knowledge, not by sub-string matching.

  • Extracting and categorizing concepts allows for knowledge-based searching.


Web of concepts

“Web of Concepts”

  • Extract raw data (phone numbers, addresses, prices, etc.).

  • Link related entities together (e.g., link actor to movie).

  • Categorize information about each entity (what does this store sell, what has this author written, how highly are they reviewed?).

  • Search engines discover webpages, parse them into objects and data, process them and store the data, updating existing entries as needed.

  • “Concept web” stored in vast databases.

    • Not traditional databases.

    • Based on graph theory, not relational model.

    • Database consists of nodes and links.


Memory cloud

Memory Cloud

  • To make this efficient we must traverse the entire graph in milliseconds.

  • One solution – “memory cloud.”

    • Store entire database within memory at all times.

  • Example: Google search “blowfish”

    • Results: Show company, encryption algorithm, sushi

    • New results: Suggest “pufferfish”


Limitations

Limitations

  • Currently only works in English.

  • Including other languages increases the complexity exponentially, we’ve got a long way to go.

  • Dissecting language to understand searches written in normal language, not just keywords.
