Product Listing Ads (PLAs) are primary online advertisements merchants pay to attract more customers. However, merchants prefer to stack various attributes to the title and neglect the fluency and information priority. These seller-created titles are not suitable for PLAs as they fail to highlight the core information in the visible part in PLAs titles. In this work, we present a title rewrite solution. Specifically, we train a self-supervised language model to generate high-quality titles in terms of fluency and information priority. Extensive offline lest and real-world online test have demonstrated that our solution is effective in reducing the cost and gaining more profit as it lowers our CPC1, CPB~2 while improving CTR3 in the online test by a large margin. It is also easy to train and deploy, which can be a best practice of title optimization for PLAs.

An organic inorganic hybrid perovskite (C_6H_5CH_2NH_3)_2CuCl_4 was synthesized successfully by solution method at room temperature and the thin film of (C_6H_5CH_2NH_3)_2CuCl_4 was also prepared by spin-coating on the quartz substrate. The perovskite and the film were characterized with X-ray diffraction (XRD), Scan electronic microscope (SEM), Atomic force microscope (AFM), Fourier transform infrared spectroscopy and Thermo Gravimetric Analyzer. Results show that the obtained perovskite has unique layer structure and good thermal stability with melting point around 243.3°C. And the prepared film appears very smooth, continuous and uniform with a grain size of 0.1 um, highly oriented with the (0 0 1) planes perpendicular to the substrate surface. Its optical photoluminescence spectrum mainly depends on the inorganic part so the bandgap can be timed by changing the inorganic composition. The carrier mobility is around0.26 cm~2 V~(-1) s~(-1) which indicates its potential application in field effect transistor with improved film quality.
