Happy April Fools’ Day!

April-1Today we celebrate April Fool’s Day. And what better way to do it than to leverage semantic resources to find some interesting facts about the holiday and a few ideas for things to do today, too?

Just like these:

What to Watch:

The April Fools: a late 60’s romantic comedy starring Jack Lemmon and Catherine Deneuve

April Fool’s Day: called a “gory, darkly comic cult favorite” from the late ‘80s.

April Fools: The day belongs to the slasher flicks, this one centering on the accidental killing of a teen, its coverup, and subsequent murders of those responsible for the original incident.

What To Listen To:

Sounds of Silence: The Simon & Garfunkel release includes the song, April Come She Will. And after this winter, that’s something a lot of people will be very happy to hear.

Ikuya Yamada, co-founder and CTO of Studio Ousia, the company behind Linkify – the technology to automatically extract certain keywords and add intelligent hyperlinks to them to accelerate mobile search – recently sat down with The Semantic Web Blog to discuss the company’s work, including its vision of Semantic AR (augmented reality).

The Semantic Web Blog: You spoke at last year’s SEEDS Conference on the subject of linking things and information and the vision of Semantic AR, which includes the idea of delivering additional information to users before they even launch a search for it. Explain your technology’s relation to that vision of finding and delivering the information users need while they are consuming content – even just looking at a word.

Yamada: The main focus of our technology is extracting accurately only a small amount of interesting keywords from text [around people, places, or things]. …We also develop a content matching system that matches those keywords with other content on the web – like a singer [keyword] with a song or a location [keyword] with a map. By combining keyword extraction and the content matching engine, we can augment text using information on the web.

Is A Knowledge Graph-Related Acquisition In Yahoo’s Future?

sdtechIs SindiceTech about to be acquired by Yahoo? Just last month The Semantic Web Blog reported on the formal relaunch of the company’s activities following the finalization of its separation from its university incubation setting at the former DERI institute in Ireland. Now, according to the Sunday Independent, Yahoo – which the article says had originally planned on buying the company late last year but saw negotiations collapse – may resume talks on the matter.

Yahoo, the article says, “refused to comment on the Sindice-Tech deal, calling it as ‘rumour and speculation.’” SindiceTech CEO Giovanni Tummarello also says that he cannot comment on this. He did note, however, that media, search and advertising are prime sectors for employing Knowledge Graphs. “In scenarios where there is much more (semi-structured) information than one knows how to leverage right away, Big Data graph-like knowledge management and moving from search to relational and entity search is a common theme these days,” he wrote in an email to The Semantic Web Blog.

SindiceTech Relaunch Features SIREn Search System, PivotBrowser Relational Faceted Browser

sindiceLast week news came from SindiceTech about the availability of its SindiceTech Freebase Distribution for the cloud (see our story here). SindiceTech has finalized its separation from the university setting in which it incubated, the former DERI institute, now a part of the Insight Center for Data Analytics, and now is re-launching its activities, with more new solutions and capabilities on the way.

“The first thing was to launch the Knowledge Graph distribution in the cloud,” says CEO Giovanni Tummarello. “The Freebase distribution showcases how it is possible to quickly have a really large Knowledge Graph in one’s own private cloud space.” The distribution comes instrumented with some of the tools SindiceTech has developed to help users both understand and make use of the data, he says, noting that “the idea of the Knowledge Graph is to have a data integration space that makes it very simple to add new information, but all that power is at risk of being lost without the tools to understand what is in the Knowledge Graph.”

Included in the first round of the distribution’s tools for composing queries and understanding the data as a whole are the Data Types Explorer (in both tabular and graph versions), and the Assisted SPARQL Query Editor. The next releases will increase the number of tools and provide updated data. “Among the tools expected is an advanced Knowledge Graph entity search system based on our newly released SIREn search system,” he says.

SindiceTech Announces Freebase Distribution in the Cloud (Video)

sin

With the support of Google Developers, SindiceTech has announced the availability of its Freebase Distribution for the cloud. According to SindiceTech, “Freebase is an amazing data resource at the core of Google’s ‘Knowledge Graph’. Freebase data is available for full download but today, using it ‘as a whole’ is all but simple. The SindiceTech Freebase distribution solves that by providing all the Freebase knowledge preloaded in an RDF specific database (also called triplestore) and equipped with a set of tools that make it much easier to compose queries and understand the data as a whole.”

Love Is In The Air, And On The Semantic Web

Not everyone gets to have quite the affectionate relationship with technology that Joaquin Phoenix has with Samantha in Her. But it’s nearly Valentine’s Day, and so as good a time as any to at least review some of the ways that semantic and related technologies are helping us find — and stay — in love:

  • Graphing relationships is the game at dating app Hinge, which works to connect Facebook friends with friends’ friends, using their history and likes to build a graph about each other that gets the love conversation started. The free mobile data-driven matchmaking app is available in  NYC, DC, Philadelphia, and Boston, and most recently came online in San Francisco, too.
  • Folks in search of romance also have the Freebase-powered LoveFlutter to check into. It, too, makes use of your Facebook interests and extends that with the help of the Freebase’s database to fill out other details about those interests – such as what genre of movies it is that you like – to semantically connect your interests with that of other users, and you with them. It will use that data to suggest a great first date spot for you, too. Costs range from free to $29.99 month.

Google’s Popping Up Information About Search Result Sources

Google’s Knowledge Graph took on some new work this week, driving popups of information about some of the website sources that users see in their search results.

googresultAccording to a posting at Google’s Search blog, clicking on the name of the information source that appears next to the link delivers details about that source, as in the picture at left. “You’ll see this extra information when a site is widely recognized as notable online, when there is enough information to show or when the content may be handy for you,” reports Bart Niechwiej, the software engineer who wrote up the news.

The feature’s been getting a lot of buzz. Much of the information informing Google’s Knowledge Graph comes from Wikipedia, as well as from Freebase and the CIA World FactBook. And, when it comes to a popup source of information you’re likely to see show up somewhere in most searches’ results, Wikipedia likely will be among them. In fact, observers like Matt McGee over at Search Engine Land have noted about the new feature that “the popups rely heavily on Wikipedia.”

Dandelion’s New Bloom: A Family Of Semantic Text Analysis APIs

rsz_dandyDandelion, the service from SpazioDati whose goal is to delivering linked and enriched data for apps, has just recently introduced a new suite of products related to semantic text analysis.

Its dataTXT family of semantic text analysis APIs includes dataTXT-NEX, a named entity recognition API that links entities in the input sentence with Wikipedia and DBpedia and, in turn, with the Linked Open Data cloud and dataTXT-SIM, an experimental semantic similarity API that computes the semantic distance between two short sentences. TXT-CL (now in beta) is a categorization service that classifies short sentences into user-defined categories, says SpazioDati.CEO Michele Barbera.

“The advantage of the dataTXT family compared to existing text analysis’ tools is that dataTXT relies neither on machine learning nor NLP techniques,” says Barbera. “Rather it relies entirely on the topology of our underlying knowledge graph to analyze the text.” Dandelion’s knowledge graph merges together several Open Community Data sources (such as DBpedia) and private data collected and curated by SpazioDati. It’s still in private beta and not yet publicly accessible, though plans are to gradually open up portions of the graph in the future via the service’s upcoming Datagem APIs, “so that developers will be able to access the same underlying structured data by linking their own content with dataTXT APIs or by directly querying the graph with the Datagem APIs; both of them will return the same resource identifiers,” Barbera says. (See the Semantic Web Blog’s initial coverage of Dandelion here, including additional discussion of its knowledge graph.)

Music Discovery Service seevl.fm Launches

screen shot of seevl.fm search: Lou ReedThis week marked the public launch of seevl.fm.

SemanticWeb.com has tracked seevl’s development through various incarnations, including a YouTube plugin and as a service for users of Deezer (available as a Deezer app). This week’s development, however, sees the service emerge as a stand-alone, cross-browser, cross-platform, mobile-ready service; a service that is free and allows for unlimited search and discovery. So, what can one do with seevl?

Following the death of Lou Reed this week, I (not surprisingly) saw mentions of the artist skyrocket across my social networks. People were sharing memories and seeking information — album and song titles, lyrics, biographies, who influenced Reed, who Reed influenced, and a lot of people simply wanted to listen to Reed’s music.  A quick look at the seevl.fm listing for Lou Reed shows a wealth of information including a music player pre-populated with some of the artist’s greatest hits.
