Clustering Lexical Patterns Obtained from a Text Corpus

AAAI Conferences

This taxonomy was generated from a list of keywords which was created independently for use as an index to the home lawn care publications. The keywords were manually arranged into a generalization hierarchy. For more detailed analysis of a particular word, a concordance of phrases containing the word was generated from the fulltext search index. These phrases were then parsed using an island chart parser that could generate a semantic representation of the phrase. For example, the phrases: are parsed syntactically as: control[selective] (weeds[emerged, grass, crabgrass]) control (weeds[emerged, summer, annual, grass, crabgrass]) (2a) (2b) where phrase heads are shown as predicates with arguments in parentheses and modifiers in brackets.

New Japanese farm drone hovers above rice fields and sprays pesticides and fertilisers

Daily Mail

Japanese farmers are testing a new drone that can hover above paddy fields and perform backbreaking tasks in a fraction of the time it takes a labourer. The drone applies pesticides and fertilizer to a rice field in 15 minutes - a job that takes more than an hour by hand and requires farmers to lug around heavy tanks. Developers of the new agricultural drone say it offers high-tech relief for rural communities facing a shortage of labour as young people leave for the cities. Pictured is a farmer in Japan's Tome region trialling the new technology'Our ultimate goal is to lower rice farming costs to one-fourth of what it is now,' Hiroshi Yanagishita, President of Nileworks, the Tokyo drone start-up behind the technology, told reporters Thursday. Nile-T18 was recently tested in Japan's Tome area – a region that has supplied rice to Tokyo since the 17th century.

Startup company plans to use swarms of drones to plant trees after a wildfire - Fire Aviation


Replanting trees after a wildfire or logging operation is an extremely labor intensive and expensive task. Carrying a bag of seedlings and using a dibble bar or shovel across steep debris-covered terrain can wear out a human. A new company, DroneSeed, has a solution. They are designing a system around a swarm of drones that can plant tree seeds in places where they have a decent chance of survival. First they survey the area with a drone using lidar and a multispectral camera to map the terrain and the vegetation.

Use Of Drones & Robotics In Agriculture – DEEP AERO DRONES – Medium


Bees are getting extinct due to variety of issues such as: pollution, pesticides, fungicides, climate change, etc. Lately Walmart applied for patent with the U.S. Patent Office for drone pollinators designed to fly from plant to plant, collecting pollen from one and transferring to other. Robotics is already being implemented in strawberry harvesting, fresh-fruit picking, data mapping and seeding. The autonomous tractors might also capture a commonplace. Recently, an interactive presentation at Colorado State University, shared the overview of future of farming by the presenters Raj Khosla and Tom McKinnon. Khosla discussed the 5 R's of precision agriculture: "at the right time, in the right amount, at the right place, use of the right input, in the right manner."
