Google Launched New Search Algorithm “Hummingbird”

What type of “new” search activity does Hummingbird help?

Conversational search” is one of the biggest examples Google gave. People, when speaking searches, may find it more useful to have a conversation.

“What’s the closest place to buy the iPhone 5s to my home?” A traditional search engine might focus on finding matches for words — finding a page that says “buy” and “iPhone 5s,” for example.

Hummingbird should better focus on the meaning behind the words. It may better understand the actual location of your home, if you’ve shared that with Google. It might understand that “place” means you want a brick-and-mortar store. It might get that “iPhone 5s” is a particular type of electronic device carried by certain stores. Knowing all these meanings may help Google go beyond just finding pages with matching words.

In particular, Google said that Hummingbird is paying more attention to each word in a query, ensuring that the whole query — the whole sentence or conversation or meaning — is taken into account, rather than particular words. The goal is that pages matching the meaning do better, rather than pages matching just a few words.

I thought Google did this conversational search stuff already!

It does (see Google’s Impressive “Conversational Search” Goes Live On Chrome), but it had only been doing it really within its Knowledge Graph answers. Hummingbird is designed to apply the meaning technology to billions of pages from across the web, in addition to Knowledge Graph facts, which may bring back better results.”

So, we should not say Google Search is just exact words search. In fact, now is more than that. Much closer to semantic search.

Deciphering the Semantic Web

What is the Semantic Web? Technology Voice recently interviewed some leading Semantic Web researchers with both academic and industrial experience to find out what it is, why it is needed, and what are the exciting applications of semantic technologies.

The results of these interviews are captured in our exclusive 44-minute video, “Deciphering the Semantic Web“.”

Written and produced by Tom Murphy. Produced and directed by Julie Letierce.

Public View of RDA Records

There are new fields created in MARC21 to cater for RDA (for example: 264, 336, 337, 338). Libraries have to make a decision on how and what to show the information of these fields in the public catalogue. Kent State University Libraries has decided to show each 264 fields in one line with specified labels; and omit the 337 field and show the 336 and 338 together in one line with the label “format”

Here is one example.

Metadata can be data

Metadata describes data.  Data in here means something useful to the users.  Metadata helps the data consumers (library users, staff of library or IT dept)  achieve certain purposes.  But metadata itself can be a kind of data.

Read this interesting article “Metadata, So Mom Can Understand” to know more.

Our bibliographic metadata (e.g. cataloguing records) does not only help users to find the resources in our collection, it can be ‘data’ in the context of Semantic Web.  This is one of the arguments supporting the Linked Library Data movement.

Alexander Street Press

Mr Stephen Rhind-Tutt gave a talk

“Increasing functionality and usage of video so it may gain its rightful place in the academy”

in the Keynote of Session 124 of IFLA 2013

The talk shared the ways the company give a new life of the hidden video collections delivered on the web.  By adding annotations and semantic search features, videos can ‘perform’ the best on the web.  The talk is full of insights. There is a video available in YouTube recording a similar talk by him earlier this year.

Happy watching..
