We describe a software tool named "Rootvole" which extracts semantic entities and numerical values from natural language queries (textual or vocal). It has been used successfully in a variety of projects, such as an Android app to search a second hand car database or searching in a TV program.
Based on an analysis of our voice search projects, we were looking for a more lightweight solution compared to those found in the literature. For general processing of voice queries we developed a text parsing library that can be used to match text with semantic concepts.
The Rootvole framework is implemented as a Java library. The extraction algorithm is based on a form of a parsing expression grammar, where we generate the expressions to be detected beforehand by regular expressions and store them in a vocabulary.
The following items get distinguished:
The talk motivates the field of voice search, introduces the Rootvole keyword spotter and illustrates its use in different domains and applications.

Digital marketing can benefit greatly from well designed, adaptive metadata architecture that supports the whole life-cycle of the marketing information.
If you consider using metadata for digital marketing and want to benefit from the full potential, then this presentation is essential for you.
It gives you a model how to capture, manage and use the four fundamental type of metadata for intelligent content targeting.
Four fundamental type of metadata are derived from the content lifecycle phases:
I call the model "Digital marketing 360 metadata". It ties together the four fundamental metadata types of content life-cycle. Leaving one type out – or viewpoint one may call it – causes a distorted or incomplete picture of what content should be shown to each persona or registered consumer.
The concept tells you what your customers care about, and you should too:
Placing the good metadata on web pages
So, all this valuable metadata should be collected, contextualized, structured and then published on the web pages in order to get boosted SEO and to provide more meaningful search results to hasty consumers.
I bet, most of the needed semantic data about products and their "consumer context" is available somewhere in your company’s product and marketing processes, but not retained and piped through the complex (disconnected?) systems to the web page publishing as a high-quality metadata.
That has been the case in the most of companies whom I have consulted. What comes to the structured metadata, there are schemas published and clear guidelines to follow - by Google for example - in order to inject metadata to the HTML markup in your publishing process.
But why are Google and other big boys giving this all out? I guess this is part of their Knowledge graph initiative to semantically model the entire world? But, it makes you also wonder if what they says is biased, since it is in their interests to grab as much as possible meaningful (codified) data from your pages to enlarge their knowledge graph and also – most importantly – to make money from your data.
Shaping up the data quality, harmonization of identifiers for business objects, integrating data flows and establishing a common terminology can take half a decade or longer. It is about educating people and revamping the corporate culture, and not about buying new technology.
However, by choosing the right approach and using semantic technology savvy tools – the data integration may be much easier than you think. SKOS compliant tools with Linked Data integration give you a kick start.

Holistic approach is mandatory when designing data models:
* business drivers and scenarios (focus on data abstraction and objectives: what is needed and why? where do you want to go?)
* user stories (focus on user research: how to use the data? who needs the data?)
* information flow (focus on process: identify systems, how data flows? what data and where? )
* data/information sources (focus on integration, inventory and feedback: where and how to get? what is it in details? how to improve it?)
